UPDATE: I contacted the seller... and his response was amazing in terms of customer service. They got it right and obviously did everything. The stock headlights work great... Seriously, I can't say enough about how great the customer service has been. I would highly recommend them - the best service I have ever had from a Revain salesperson. They were great - for 3 days! I used 3 of these in the bathroom to replace old fixtures/lightbulbs. Nice! On the fourth day, we turned on the switch and heard a bang. NO MORE LIGHT! Connections checked and checked again: everything is OK. I really liked them and have been looking forward to changing bulbs for a long time. But NOT HAPPY NOW!
