2011 Buick Regal Light Bulb Sizes/Styles

I have a left side turn signal out, took out the access cover in the trunk, 2 thumb screws revealed, now what??

Change the bulb?

IDK, havent had ours apart yet. I can look at it tomorrow.


Welcome to RF!

Is this true, the reverse lamps and rear running lamps are both 3157 bulbs (ie. dual filament)?

I wouldn't be surprised just take your reverse lamps and try it out...

Thanks for the bulb sizes though! going to order some LEDS when i get my regal!

Good info thestepchild. Could you make this a stickie for future reference?

Once you get the "covers" off in the trunk and you can get to the two plastic screws, just unscrew those and the taillight pops right off. The third piece holding the taillight is just a pressure fitting and it will pop off on its own.

Yep, 3157. Swapped my reverse lights & license plate lights for LEDs the day I brought my car home

Do you get any faults when replacing the bulbs with LED lights?

Check out the videos here for "How to" on the 2011 Regals. Great source of information.
