Does any one know the bulb sizes for the license plate light, brake lights, reverse light and front turn lights? I'm looking to do a led upgrade. Also does anyone have any advise?

Lic is 194.
Reverse is 921 if non led stock tails.
Fr Signal is 3157A amber.
Rr Tails is 3157. You will need Red LEDs to make it look correct

You will also need to do load resistors on all circuits.
If u do frt signals....you need 2 load resistors for each side. One fpr park circuit and one for signal. They use the same multi element bulb. 3 wire plug. One ground, one wire for turn and one for park.

Same for tails. They are 3 wire bulbs as well.

If you dont do load resistors, u get error messages on the dash info center. Also u get fast flash on signals. The canbus error free ones are hit or miss about working and not sending a error code.

Look into the dealer being able to do a LED prep programming. Depends on year but they can set the body control module to accept and not throw codes.

Thanks for the info. Do you happen to know what the bulb size is for the 3rd brake light.

I wasn't stating, i was asking lol. Would love to throw some white LED 194 in the license plate lights.
