My first 2 Mods!
Also installed LED bulbs on the low beams, pic shows the drivers side complete only. We’ll see how they work at night, but they look good during the day! I did some research and went with not the cheapest, diode dynamics bulbs. They have a 3 year warranty and seam very well built.

I went with them since they were a sponsor of this website and drank their coolaid on quality. Not so much. I had my first bulb failure about 1-2 year in and they swapped it out. PITA to swap bulbs on these trucks but oh well, probably a 1 off and i’ll be good. Nope, that same bulb i swapped out went dim on me like the last one 2 years later and now they won’t swap it out.
i would think these bulbs should last longer for that amount of money and they would back their warranty of 3 years on a replacement that’s less than 3 years old, pretty disappointed.
Do not buy.

I am sorry to hear about this. Are you within the 3-year warranty period for a replacement?
This issue has been reported by many Ford F-150 owners for a range of LED headlight replacement bulbs, not just the Diode Dynamics SL1.
The F-150 often has an electrical issue that is commonly seen dimming LED plug-and-play bulbs and then essentially killing their lifespan. However, this isn't the case for every owner but many truck owners have reported this.
Please go ahead and give us a call at 314-205-3033 Monday-Friday 10 a.m.- 5 p.m. CST, or shoot us an email at contact@diodedynamics.com, and our service team would be happy to help you if you're within the 3-year warranty period for our SL1 bulbs.
Thank you!
