Well, since it seems to be sort of hard to find LED guides for our trucks, were banding together and creating an ALL Generation LED bulb guide. Also we will include HIDs to make everyones life a little easier. If you have read through a bulb replacement guide you will notice that most of the LEDs bulb # is the same as the halogen bulb number say from PepBoys or Autozone.
Here is a good link also to try and figure out what sort of bulbs you need for ANY vehicle. They way they create their list can be slightly confusing though, LINK, feel free to PM me if you need additional help, Im happy to spec LEDs for any vehicle you'd like.
If you have a list of bulbs to add and high resolution pictures to upload with them please send me a PM or post and I will update this until we have a full listing for everyones truck!!
A little more on reading into LEDs as well, as I have seen most suppliers label their LEDs the same way. We will use the most popular "921" bulb
The p/n for a blue 921 as seen in the pictures below is, 921-B12:
921 <--refers to the bulb type B <-- refers to the color 12 <-- refers to the ammount of LEDs in the bulb
another example would be a red version for the third brake light which would read:
Also remember LEDs are polarized, meaning they will only work one way. If you plug your brand new LED in and it doesnt work, pull it out and insert it the other way before making an angry phone call to the supplier!
