Thought I saw a thread around here before giving all the bulb sizes but can't seem to find it now. Wanting to put LEDs in my dashlights and so on throughout my truck.

Also for the 1999 f150 headlights and fog lights the same bulb size? Wanna get new hids but never had them in my fog lights

The 99+ clusters use T5 bulbs. Here is a pic of the back of my cluster, which is an 03. All are T5 bulbs:



HL bulbs and Fogs are different. HL: 9007 Fog: 9145

 

Bingo, it's in my signature too

 

Sweet thank you
