28mm / 29mm Festoon LED Bulb — DE3021 DE3022 6612F 6614F | Vanity / Glove Box | 2 Bulbs
What is a 28mm / 29mm festoon LED bulb used for?
28-29mm festoon bulbs are the smallest in the festoon family, used in tight spaces like vanity mirror lights (the most common application), glove box lights, and some step well lights. The Sylvania 6612F / 6614F / 6615F bulbs are interchangeable with Hella DE3021 / DE3022 — both are the same physical bulb sold under different brand catalogs.

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
How do I know if my car uses 28mm or 29mm festoon?
They're the same physical bulb. Industry catalogs use both names interchangeably — Hella calls them 28mm (DE3021/DE3022), Sylvania calls them 29mm (6612F/6614F/6615F). Both fit the same socket. If your existing bulb is roughly 1.10 inches long with end caps, this is the one.
What's the difference between DE3021 and 6612F?
Brand. DE3021/DE3022 are Hella/Bosch part numbers; 6612F/6614F/6615F are Sylvania part numbers. The physical bulb is the same 28-29mm festoon and they replace each other 1:1. Our Driveon LED replaces all of them.
Will these fit my vanity mirror?
If your vanity mirror uses a small ~1-inch festoon bulb (which is the case for most US cars since 2010), yes. Check our verified fitment table above for your specific vehicle and year.
Are these CANBUS error-free?
Yes. Driveon Festoon LEDs include built-in CANBUS compatibility — no dashboard "bulb out" warnings, no flickering, no resistors required.
Why are they sold in pairs?
Most cars have vanity mirrors on both sides (driver and passenger). A 2-pack covers both. If you only have one, you'll have a fresh spare for later.
