any one know what size of the rear signal bulbs im trying to get hyper white bulbs and tried the 1156 but the side metal pins dont line up. any one know anything

 

Odd...

On mine (2000 L) the Signal Bulb is an 1156A and the Brake light is a
1157 (tail lights) the reverse bulb is a 1156...
the only difference in a 1156A and a 1156 is the A is amber...

the base of the bulb will tell you the number, too... ensure you have
the right one, might have been mis-packaged...
