Stop and Signal Car Bulbs

The exterior stop and signal car lights, whether attached at the front, side or rear of the vehicle, provide information for other road users through their signals. These types of car lights will make a vehicle conspicuous and visible with respect to its presence, position, direction of travel, change in direction, or deceleration.

Stop and signal car lights may light steadily, blink, or flash, depending on their intended and regulated function. Most of them must be fitted in pairs, one left and one right, though some vehicles have multiple pairs (such as two left and two right stop lights) and/or redundant light sources (such as one left and one right stop light, each containing two bulbs).

Exterior stop and signal car lights

Front position lights: known as parking lights and front sidelights, provide nighttime standing-vehicle conspicuity. The car bulbs used for this type of lights are designed to use little electricity so they can be left on when parked for prolonged periods of time.

Daytime running car lights: some countries permit or require vehicles to be equipped with daytime running lights (DRLs). Depending on the regulations of the country for which the vehicle is built, these may be functionally dedicated lights, or the function may be provided by the low beam headlights.

Side marker lights: amber light color on front and red light color on rear side marker lights are required. These side-facing car lamps make the vehicle's presence, position and direction of travel clearly visible from oblique angles.

Direction indicator lights or turn signals are blinking lights mounted near the left and right front and rear corners of a vehicle, and sometimes on the sides or on the side mirrors of a car. They are activated by the driver on one side of the vehicle at a time to advertise intent to turn or change lanes towards that side, or used simultaneously as a hazard warning signal to warn other drivers of a vehicle parked on the road or a faulty car.

Side turn signals: in most countries, cars must be equipped with side-mounted turn signal repeaters to make the turn indication visible to the sides of the vehicle rather than just to the front and rear of the vehicle.

Rear position car lights or tail lights: conspicuity for the rear of a vehicle is provided by rear position lights also called tail lights. These are required to produce only red light and to be wired such that they are lit whenever the front position lights are lit, including when the headlights are on. Rear position lights may be combined with the vehicle's stop lights or be separate from them. In combined-function installations, the lights produce brighter red light as stop lights and dimmer red light as rear position lights.

Stop lights or car brake lights: red steadily lit rear lights, brighter than the rear position lights, are activated when the driver applies the vehicle's brakes and warn vehicles behind to prepare to stop or a decreasing travel speed.

Rear fog car lights: cars are equipped with one or two bright red "rear fog lamps", which serve as high-intensity rear position lights to be activated in poor visibility conditions, as fog or heavy snowing, to make the vehicle more visible from the rear.

Reverse moving car lights: their function is to warn nearby drivers and pedestrians of vehicle's rearward motion, and to provide illumination to the rear when the car is in reversing mode.

Rear registration car plate light: the rear registration car plate is illuminated either by a single or a pair of white lights. It is designed to light the surface of the plate without creating light directly visible to the rear of the vehicle.


interior and convenience car lights

Interior and convenience car lights

Most cars have two of "dome light", or "courtesy light", located in front and middle of the car cabin, near the ceiling of the passenger compartment, to provide illumination by which to fasten seatbelts and enter or exit the car. On our days we can talk about the dome lights panels where, apart from the courtesy lights, we will find switches for map reading interior lights that are aimed at specific passenger positions and allow for reading without glare distraction to the driver and like an extra light for drivers map reading when car stopped.

Car interior lighting has been added at the bottom edge of the dashboard, illuminating the floor for front passengers, or underneath the front seats at the rear, illuminating the floor for rear passengers. This type of convenience lighting approach is also sometimes used to illuminate interior or exterior door handles, exterior step running boards, or electric window switches.

Some cars have "approach lighting", lights that illuminate the ground outside the doors, in the exterior mirrors or lower edges of the doors.

Other types of interior and convenience car lights are the lights in the car trunk, light in the engine compartment, and lights in the glove box and other storage compartments.

And to not forget about that most instruments and controls on a car dashboard are illuminated when the headlights are switched on, and the intensity of dashboard light can be adjusted by the driver for comfort.



For all these types of car lights listed above, in this section you will find all kinds of car bulbs for stop, signal, position, interior comfort and auxiliary lights.

Car bulbs for stop, signal, position, side, reverse, interior lights


  • Stop Signal Car Lights

    A car has several stop and signalling lighting devices: route light indicators, brake lights, side marker lights, hazard warning lights, reversing lights, rear fog lights and the car position lights. These signalling devices are used by drivers to communicate to other road participants what they intend to do. Light signals give a attention warning to other road users that you intend to make a specific manoeuvre.

    Car signalling light bulbs

    Giving appropriate car light signals at the correct time and place, and correctly interpreting the signals of other road users, is important for the safety of all traffic participants.


    Your car light signals must be given in a proper time before you start your car manoeuvre and for long enough for their meaning to be clear to other road users.


    Indicator car lights are amber colored and can be located at the front, the rear, and at the side of the car on both the left and right sides. You will use your car indicators lights to show an intended change of direction, whether turning left or right or steping into traffic. Use the indicator car lights properly, giving other road users plenty of time to react and adapt to your signal. Once you have completed the manoeuvre, make sure the indicator lights has been cancelled, or you may confuse other road users.


    When you press the brake pedal, two rear warning lights are activated. These lights are called brake lights signals. This signals are showing to traffic behind you that you are slowing down. The brake lights are in red color and are more powerful than the position car lights.


    When you turn on your hazard warning lights, every indicator light of the car has begins to flash. You turn on your hazard warning lights when you need to warn other road participants of a hazard as your car has technical difficulties and is obstructing the traffic, or to warn other road users of an ahead unexpected event or obstacle.


    When a car is put into reverse gear either one or two white lights are activated at the rear of the car. These are the reverse mode car lights.


    Car front and rear position lights and car side marker lights, provide nighttime standing-vehicle conspicuity and mark the outer limts of the car. Together with rear fog lights they are completing the car signalling lights types.


    The next section will introduce and offer you all the 12V metal base car bulbs that you may need to replace a broken signalling car light from stop and signal category.

  • Mini Series Car Lights

    Car signal lights have an important safety function. They demonstrate deceleration and a change in direction of the vehicle, and make the car more visible to other road participants when it is dark or during poor visibility.

    Miniature glass wedge car bulbs

    Miniature series glass wedge car bulbs are used for front and rear position lights, indicator lights, side marker lights, parking lights, side turn signal, rear fog lights, reversing lights, rear registration plate lights, trunk lights, and interior comfort lights. They are part of stop and signal car bulbs category.


    This glass wedge base small car bulbs type used by cars have the purpose of increasing the vehicle's visibility, allowing other road participants to see its presence, position, vehicle size, direction of travel, and its driver's intentions.


    A wedge base is a type of electrical connector used as a fitting for small light bulbs. It is similar to the dual pin connector, except that the two "pins" are the same wires that extend inside the bulb, rather than being rigid, and the wires are bent up onto the sides of the base, where they make contact with the bulb socket.


    The glass wedge car miniature bulb is inserted and removed with straight in or out force, without turning on  as with metal base. Sometimes the glass wedge car small bulb may have dual filaments, acting as both a low-wattage tail light or parking light and a higher-wattage brake light or turn signal. In this case, one has its contacts near the center of the base, and the other toward the outside edges, so that they cannot be accidentally swapped. Along with putting contacts on the opposite or alternating sides, this gives the glass base rotational symmetry so that the user does not have to determine the exact position of the old broken bulb before inserting a new replacement car bulb as the inserting position can be randomly choosen.


    The ECE types for the miniature glass wedge car bulbs are: T5, T10, T15, and T20. They are in clear type and orange colors models and may have double filaments for dual car lighting tasks.

  • Festoon Car Lights

    Festoon 31mm, 36mm, and 41mm car light bulbs are used for front and rear position lights, side marker lights, indicator light signal, rear fog lights, reversing lights, rear registration plate lights, interior comfort lights, dome lights, map reading light, inside mirror lights, footwell lights, and trunk light. These festoon light bulbs types used by cars have the purpose of increasing the vehicle's visibility, allowing other road participants to see its presence, position, vehicle size, direction of travel, fulfilling the car driver and passengers interior comfort and, generally speaking, showing the driver's future intentions of following the road.

    Festoon halogen and LED car light bulbs

    The word "festoon lamp" generally refers to a double-ended miniature lightbulb. The festoon car lamps focus on safety and weather resistant with great IP ratings.


    The car festoon lamps design and fabrication it is about using a small incandescent lamp soldered on metal trims. The incandescent filament of car festoon bulbs is linear. The philosophy of festoon light bulbs is about linear lighting comparing with the spot radial lighting emitted by regular round light bulbs.


    In automotive industry the festoon halogen light bulbs are manufactured in three length dimensions: 31mm, 36mm, and 41mm. The electric power used by halogen festoon car lamps it is of 5W and 10W. In the case of LED sofit car lighting bulbs the elctric power used is 0.80W much less than standard halogen sofit bulbs.
