Another simple fix for ‘99-05 Jetta owners out there is the headlight turn signal bulb. Yet another opportunity to save some cash and a trip to the dealer!
Step 1: Remove Headlight Sealing Cap
There are two plastic sealing caps on the back of the Jetta headlight. One covers the main headlight bulbs, while the other protects the turn signal and fog lamps. That’s the one we’ll be removing. There is a clip on the top end of the cap. Carefully push down on that clip to unlock the cap from the headlight assembly. I broke the clip off on mine when doing this (I can’t stand the plastic pieces in cars today lol). But the fragility of the plastic is probably due to the cold temperatures we have right now in Cincy.
Step 2: Unlock Bulb Holder from Assembly
Next, reach into the headlight assembly where you will find the holder containing the turn signal bulb. Rotate the holder counterclockwise to unlock it from the assembly. Carefully pull the bulb out, replace with your new bulb, and reverse your steps to complete the installation.
Step 5: Grab Your Favorite Beverage
Stand back and revel in your car repair prowess. The replacement bulb model number is 3357/3457 (amber or clear) View a photo with model number of all bulbs for reference.

I have a front right turn signal out on my 2005 Passat. Will these directions for the Jetta work in my case? Thanks!
Hey Nate, the Passat headlight may be similar, so it could get you part of the way there. I’m not sure however. I suggest you head over to the B5/B5.5 Passat forums on VWVortex.com and post your question. Guys over there have tons of info and are willing to help out. Hopefully Matt and I will be able to start doing how-tos like these on all the models, but for now, we’re restricted to our own vehicles. :D
I have an 01 jetta and the left blinker works as a blinker, but not as a marker light at night. Is it a double filament bulb or is there something wrong with my wiring harness?
Hi Austin, is it the turn signal bulb in the headlight assembly or on the side of the bumper?
