I'm a new F150 Lariat FX4 owner and new to Ford. I'd like to replace the mirror puddle lamps with red LED's to give a red glow on the ground and may add running board LED's later on. It seems that F150LEDS quality is questionable. Does anyone know what the size or model number of is for that particual bulb. I'll try to find another source.

Thanks in advance-

 

What year?
The newer ones don't have bulbs, just LED chips that can't be changed.

 

I'll bet you $100 it's a 2017.
Something about the way he asked the question is just giving me that vibe.
He used all the words like, FX4, Lariat, puddle. Those are all clues!

 

Actually I found what I was looking for. The only catch was one of the flat blade pins was turned 90 degrees from the plug harness. A quick bend with pliers to get it oriented was all it took-
