Hi Guys!

Brand new to this site, so hopefully I'm not asking a previous question. Still trying to figure this all out.

I recently installed LED's on my 2010 F150. I did the map lights, and two of the three lights in the third brake light (the third bulb wasn't included in my shipment). I was too anxious to install them, so i put two of the three in. I installed the two end bulbs and left the middle bulb as the OEM bulb. The new ones light up, but for some reason the OEM bulb doesn't shine anymore...

I tried installing a different bulb incase it was the bulb and I got the same result - nada thing. The wiring looks to be ok and the socket/connection looks good too.

Any idea why the middle OEM bulb took a dump on me?

If it helps I used these as the end bulbs from superbrightleds -
194 LED Bulb - 6 SMD LED Wedge Base Tower Cool White

 

silly question but when you hit your brakes the middle OEM bulb does not work?


I installed the two leds for the cargo lights but left the brake light oem

 

Correct. I'll hit the brakes and I get nothing from the OEM bulb.

 

Ommmm ... Only the center bulb is the stop light. Are you holding the brake pedal and checking the light at the same time? *As should be done for checking the stop lights.

As stevebass4 noted, the two outside bulbs are the cargo lights.
.

 

i'd get another regular bulb and try it or test the oem bulb with a meter - who knows maybe the filament broke when you took it out

 

Check for voltage at the bulb socket with the brakes applied.
