Exactly what I needed
Replacement headlights were just the ticket for dressing up my 2008 Pontiac Grand Prix. They were on time and under budget and easy to install. I have had quite a few positive comments.

I was able to install the headlamp assemblies per your "How to video" and saved myself $100 that the dealer wanted to install them. The headlamps look absolutely awesome and what a difference when driving at night. I can actually see the road once again.
If you are thinking of having someone clean your headlamps to reduce the fogged up appearance I would say don't waste your time and money. I had it done twice to no avail and it cost me what I paid to replace them.
I would recommend these headlamp replacements to anyone!

Great Pair!
I want to thank you for getting the headlights to me so quickly. The added value of having new bulbs and wiring already in place was terrific. The lights went in easily and make the car look like new. Priced right, shipped quickly, and pre-wired... a great pair of headlights from a great company.
