Product Overview: S7-6-12L Festoon LED Bulb (SV7)
The MIDCARS S7-6-12L is a 7mm festoon (SV7) LED bulb with a dual-face optical array — SMD 3014 LEDs mounted on both sides of the PCB deliver wide, even 360° illumination from a slim 7mm-diameter tube.
It is a direct replacement for dim halogen festoon bulbs in dome lights, reading / map lights, license plate lights, trunk / cargo lights, door / courtesy lights and vanity mirror lights. Available in five standard lengths (29 / 31 / 36 / 39 / 42 mm) with a clear shatterproof PC tube, wide 12V / 24V input, 50lm output and a choice of 6500K white, 3000K warm white or 4500K neutral white.

Frequently Asked Questions
What does this festoon bulb fit?
It is a 7mm festoon (SV7) LED bulb available in 31, 36, 39 and 42mm lengths. It fits dome lights, reading/map lights, license plate lights, trunk lights, door/courtesy lights and vanity mirror lights that use an SV7 festoon socket.
What is the dual-face design?
The PCB has SMD 3014 LEDs on both sides, so the bulb emits light in a wide 360-degree pattern instead of only one direction - brighter and more even coverage in reflectors.
Which length do I need?
Measure the distance between the two metal end caps of your current festoon bulb. Choose 31, 36, 39 or 42mm to match. The most common interior lengths are 31mm and 36mm; 39mm and 42mm are often used for larger dome or plate housings.
What voltage and color temperatures are available?
It runs on 12V or 24V and is available in 6500K white, 3000K warm white and 4500K neutral white. Custom voltages and colors can be made for OEM/ODM orders.
