I am gonna replace the bulbs in my instrument cluster panel with LED's..but I need some help getting the right size LED so it will fit correctly. I have a 1992 Jeep Cherokee and the bulbs I am replacing with LEDs are Sylvania 74 and Sylvania 37. Could someone tell me what size of LED i need to get and what shape would do the best (i.e. round, flat, square, etc.) Thank you much!

I would make sure you get good measurements on the bulbs....I bought some LED bulbs for my stereo and they were a bit longer than my other bulbs...but I did here from the company that you can sand them down a bit.

Check out Superbrightleds.com ....that's where I got mine.
