SPECS AT A GLANCE…
Very bright and great quality fit, Danny was in the ball with customer service and very quick and efficient, needed a decoder set for thw fog LED fog lights but once Danny sent me those they work amazing and are very bright!
Worth every penny. Great visibility, without oncoming traffic flipping on their brights at you. Will be buying more for future vehicles
I was a little hesitant at first about the cost of upgrading my lights but wow I am so glad I did. I drive 500-600 miles a day 5 days a week and found my stick halogen lights just weren’t bright enough. I changed my low beams to the 60w LED and my fog lamps to the 40w LED and I can see great and don’t even use high beam anymore. What a difference these LEDs are easy to install with a nice crisp clean projection. I love them and only sorry I didn’t do this sooner. Danny was a great wealth of knowledge and made this a quick easy decision.
How bright are these fog lights? let me tell you a story. I was having a new grille put in my grand cherokee and i asked the shop to swap out these bulbs, and the headlight bulbs while they had the bumper off. the shop swapped the plugs around on the headlights so they wouldn't turn on. I didn't actually realize that at first, because i had the fogs on and they lit up the ground like it was 8 AM, not 8 PM
Easy to install plug and play. Zip ties work with headlight but foglights have nothing to zip tie to so need some tape if u wanna keep it secure. DRLS do not flicker at all. Light output is very good but not great like my HIDS b4
I installed the low beams. They are a Huge improvement over the stock halogens on my 2017 Ram 1500 SLT. Literally, night and Day.
Very happy with these bulbs in my 2016 Ram 1500 and very happy with the customer service. Fog lights and high beams are next.
Ordered a set of led plug and play bulbs from Danny and I must say they look fabulous, Danny was a great help, next to order the fogs!! highly recommended!

Fogs looks great! Much better than stock halogens. Easy install took maybe 30 mins pulling back felt inner fenders liner and swap out.
No experience with actual fog/snow yet but they throw light much better than stock. Also shipping was super quick! Thank you DL!
