my illumnation isn't working for my headlights
 

So i did the " Fog light mod" everything works fine but four months later my green led in my light switch won't work sometimes i can just bang the light switch and then the green leds will come on ....What wire should i be looking at or it could be a short..

Can you post some specs on your truck or complete your profile ?

yea sscully i have a 2003 f150 xlt

I think that one is like what's described in these captions:

But you should add a signature with more info than your profile shows, like engine, miles, mods, any major repairs...

Sounds like an issue with the LED in the switch itself, not a loose wire ( although could be ).

The Light blue w/ red stripe wire is the instrument illumination circuit in the truck from the dimmer switch.

Only works for those who do not have signatures turned off....

This is actually what the garage feature is for.
If it does not fit in one of the 5 category boxes ( millage is a different section ) there is always the [Tell the world a little bit about your vehicle] section for non modification items..:thumbsup:

That's why I advocate a signature. ;) Once I start typing a reply, I don't want to have to check a garage to find the truck's specs.
