How to install (60 seconds)
- Pop off the lens cover. Use your fingernail, a credit card edge, or a small flathead. Gentle pry — lenses snap back in easily.
- Pull out the old bulb. Festoon bulbs sit between two spring contacts. Pull straight out (no twisting).
- Insert the Driveon LED. Push the LED into the spring contacts. LEDs are polarity-sensitive — if it doesn't light up, flip it 180° and re-insert.
- Test, then snap the cover back. Turn on the light to verify, then click the lens cover into place. Done — total time 60 seconds per bulb.
Frequently Asked Questions
What cars use 36mm festoon bulbs?
36mm festoons are less common than 31mm. They appear in some European cars and full-size American vehicles for dome lights and certain trunk/vanity positions. Check our fitment table above.
How do I tell 36mm apart from 31mm or 39mm?
Measure end-cap to end-cap. 36mm = roughly 1.41 inches. If your bulb is 1.22 inches, that's 31mm. If it's 1.54 inches, that's 39mm. When in doubt, our multi-size kit covers all interior festoon sockets in one purchase.
Is 6418 the same as 6411?
Yes — same 36mm festoon, different brand catalog numbers. Our Driveon LED replaces 6418, 6411, and DE3423.
Are these CANBUS error-free?
Yes. Built-in CANBUS compatibility, no dashboard warnings, no flicker.
