I've searched and looked and still can't find the correct bulb numbers for the Map lights and for the rear dome light in a supercrew. Can someone please either give me links or bulb numbers please.

 

Map - 906
Dome - 578

 

I put 194's in my front maps and for the rear dome, I went with a 44MM festoon. I think it calls for a 42MM but it is a little tighter w/ 44. If you have any more questions about LEDs....look me up on a PM. I changed a lot of my lights to LEDs .

 

I just used the sylvania website. they have the numbers for every bulb on the truck. I got mine from VLED.

 

^ yeah I use sylvanias, but got mine from frickenbrite.com

 

if you searched you would find it... bich

 

You could also get an L.E.D kit made by Putco if you can find them in stock.. I have a set in my truck, there worth the money. 18 times brighter than stock.

 

Just to make sure before I order, I'm wanting to replace the front and rear push button map lights on my 2004 supercrew with roof rails. Will these fit as a direct replacement? Thanks.

I have these in the maps:

I have this in the dome:

I am extremely pleased. Don't get anything but SMTs. I also have SMT cargos, plates, front markers, and switchback turnsignals (to match the HID headlights) as well. I've been meaning to post about my switchback front turns: http://www.v-leds.com/Shop/Control/P...32245236241246 They are very unique, appearing 6k HID white for parking lights, amber for turns, and appear clear when not lit. Far and away better than silverstars or chromed incandescent ambers.

Oh, BTW, THE perfect plate bulbs: http://www.v-leds.com/Shop/Control/P...34241232241250 They light up the tailgate, so bright. They need a little tweaking for the install to work just right.
