P.S. Your post should be information the OP utilizes in making his decision.
I too researched the hell out of bulbs, brands and decided to go with Underground Lighting because of your post and the fact they are a forum sponsor. Heck, Nick at GotExhaust and my posts about him should clearly tell you how loyal I am to sponsors.
Unfortunately, my experience with Underground Lighting was not near as positive as yours. And the ticket from the county sheriff for a non-functioning headlight was just icing on the cake. This was my first ticket in 29 years and it didn’t set well over something that was not my fault (the fan was clearly not working on the LED that was out).
I’m getting ready to order a set for my daughter-in-laws new 2020 Ram and actually considered giving UL another shot but got as you can imagine am a little shy about installing something in her truck that could be an issue on a dark country road.
You bought Low beam, high beam, fogs and switch back bulbs. You had an issue with a low beam and never reached out for help for what ever reason. If you are really serious in wanting LEDs for your daughter's ram I Will sell you one at cost and cover the shipping. I am here to always help my customers and stand behind my products and company. Let me know and Ill make it happen.
