Flipping through the owners manual I found that the park/turn signals are 3157AK. Now my previous Mazda6 had a similar weird designation for just a regular old 3157 bulb. So I went out and bought two twin packs of Sylvania Silverstar 3157A/4157A bulbs, as the blueish tinge when not lit would go great with the Marine Blue.

So I take what I think is the easy route and pop out the taillight first, why couldn't DCX just use standard screws instead of these plastic push pins? I gouged the bottom one up a fair bit in trying to get it loose enough to grip with some needle nose pliers. Anyway, I pull the bulb out of the rear turn signal and guess what I find?

Sylvania 3757

No 3157, no 3157A, no 3157AK, no 3157whatever. 3157 and 3757 have two different bases (Mainly just the tabs off to the side of the base are oppositely offset, rather than the 3157 which are the same on both sides.

Quick search of LXForums and I find the 3757 is a tradition for Chrysler, but in other vehicles that have the 3757 bulb, actually call for it in their manuals. Also from the same forum, it says the tabs can be filed down on the 3157 to fit the 3757 base. I'm going to see if that works.

It's already mentioned in the manual, but the reverse lights are 921s and the license plate lights are 194s (Only mentioned as W5W in the manual).

Shaved down the tabs on the 3157s and the snap securely in place and light up properly. Very minor change on the rear.

As for the front ones, looks like I have to go through the fender well, something I am quite used to after having the Mazda6. So the front bulbs are saved for another time.

Very nice. This is a MOD. I wonder if we can get a moderator to move this to the right category. If not, would you mind re-posting it in the Visual Modifications forum?

Do you have any pictures of the process? Pulling the tail-lights sounds like a chore. Any suggestions for us novice, under experienced types?

I like that blue!!!

Yeah wasn't intending to actually change the bulbs until I found that thread on LXForums.

I found an easier way of removing the taillights. Take two flat-head screwdrivers, long-handle perferred, and there are two notches opposite of each other on the base of the plastic pushpin. Wedge both screwdriver tips underneath the inner pushpin and pry outwards, then turn both screwdrivers simultaneously in clockwise or counter-clockwise and pry again. The inner pushpin should be exposed enough to take some needle nose pliers to the stem if the pushpin itself doesn't come completely out as is. The base of the pushpin pulls straight out with the inner one removed.

Then grab the edge that had the pushpins, pull it directly away from the vehicle, it sits on a small lip and then wiggle to pop the two plastic ball studs that secure it on the outside of the lense assembly.

By the second light it has become second nature.
