Not only is the product solid, support both during and after the process was great too!
1. I used the online tool to request assistance with questions about 35w vs 55w
2. I promptly got a response with a time for a scheduled call back
3. Got my call and questions answered
4. Placed order online
5. Realized they were local and was able to change from free shipping to local pickup
6. Picked up & installed
7. Had an issue with humming noise in speakers and one light not working after install
8. Called support, answered within 10 seconds and rep was very knowledgeable. He knew exactly what it was and told me to swap polarity on the resistor.
Only a select few Silverados have this reverse polarity and in under 2 minutes he diagnosed and walked me through fixing it.
Lights look amazing and I can see at night much better. Would not hesitate to recommend. I will be ordering my fog lights and high beams from them as well.
