I tried searching the forum but couldnt find the answer. I have a 04 yukon denali that has a very dim gauge cluster. I saw tutorials on how to diy the bulbs and steppers but in my research i hit a wall. I dont know what bulbs i can use. Besides 12v obviously. How bout if i wanted to change the color? I looked all over And havent found the info. Found a cluster repair kit online for $60. Comes with 10 bulbs and 6 steppers but no info on bulbs. I hope someone can help me. Thanks in advance
