2003 Impala headlights
After watching 1A Auto video I bought headlights and just snapped them in. Best thing I have done in the past 10 years.

CHEVY IMPALA REPLACEMENT HEADLIGHT ASSEMBLIES
I received the headlight assemblies from 1A Auto and installed them - very easy. Then I took the car to my mechanic to align the headlights. The scanner indicated that the lights were too dim. I contacted 1A customer service and was told that the bulbs are usually not included, and the ones that I got must have been test bulbs from the supplier. Since I threw out the old bulbs (dumb move), now I have to buy new ones. Hopefull this will all work out OK

perfect fit.
The headlights were an exact replacement and it only took a few minutes each side to replace. I would definitely recommend these from 1A Auto. Shipping was fast and packaging was excellent so nothing was damaged during shipping. One extra bonus, it says in the description that the bulbs were not included, but they were and that made it even less work for the installation.

Fantastic!
They arrived fairly quick and were easy to install. It fit like a puzzle. Now I'm more visible on the road. Also a plus, it took a couple of years off the car. Would highly recommend 1aauto. Thanks guys!

Replace the driver side low beam light worked for 2 days and now wont work i checked the bulb it relit then the next day went out again now wont come back on i need help???

BEST ANSWER: The one thing that I can think of first off would be to make sure the connection to the bulb is good. I would also check to make sure the bulb is still good. My next step would be to take a meter and make sure you are getting power to the light.
