Im referring to the 97-03 units, but im sure its the same for newer ones. Lcd displays in themselves are not very bright, that is why they are backlit. It uses normal incandescent bulbs and while you can replace with that, why not go the led route and never have to do it again and end up with a brighter display. I have not done it yet because mine still works, alot of people on here have though, and maybe they will chime in or do a write up.
