i have an 03 and trying to replace all the instrument cluster/light switch/ac controls bulbs to leds. i went to superbrightleds.com and did some research on exactly which bulbs i need and well the b8.4d-bhp bulbs i got fit but not snuggly and i can only get about half the bulbs to work? wrong size and also would like to know which bulb is for the lights switch and the ac controls lights.

 

try pulling the leds that dont work out and turning them 180*, leds are polarity sensative

 

i tryed the led route and found they are just not bright enough in guages even with multi led bulbs.

 

The LED's in my '01 are doing very well. They are just as bright as the factory bulbs. I have a thread in 98.5 - 02 Aftermarket section.
