The one star is in no way reflective of the product itself. The light felt and looked high quality. They just do not work on the Cadillac DTS. They light up amber as DRL's and flash amber when they should light up white as DRL's. The application chart said they are compatible and that is my only gripe. Anyone who has ever changed any of the front lamps on this car knows how much of a pain it is. Call a dealer and ask how much to change front lamps.Lasfit answered the phone right away and was very helpful. They were going to send me different lamps because they thought i was sent the wrong ones. a few days later they emailed me to say they don't have switchback lamps that will work for my vehicle and offered a refund. I am not looking forward to doing this again. At least i knew not to re-install the stamped nut on the back of the headlight housing when I changed head lamps a few years ago. I won't have to remove the wheel well linings.

Lights just clicked in and you could immediately see the color and brightness difference between the old halogen and new LEDs.

The first thing is read the product information.These bulbs are polarity sensitive. If the LED does not light up after inserting, simply remove it, flip the direction and reinstall. Since these bulbs built-in Intelligent Temperature Control, if you use for a long time (a few vehicles maybe 2-5 minutes, it depends on year/make/model and temperature) may happen hyper flash, please turn off and cool 1-2 minutes, they will work normally again.

I hate the old dim yellow halogen bulbs. My car is a 2008 impala. Replace the front halogen turn signal bulbs with these wow what a difference they are white in cruising mode then flash super bright amber in turn signal mode. It seemed like before I installed are use I would put my turn signal on, and people would just sit there like they didn’t see them. Now when I put my turn signals on people pull out in front of me right away, I guess they can see them now, I really don’t know how you could miss them. I highly recommend the switchbacks. Definitely a two thumbs up will definitely purchase again. As for longevity that’s to be seen. I’ve had them now approximately two months with no problem..

These lamps,unlike many others,did not require any modifications in order for them to work. Others stated a load resistor will be needed for proper operation. These were plug and play and work perfectly.

What makes these much brighter is the white perimeter lights stay on when signalling with park or head lights on. This is different behaviour that's growing on me. The other nice thing is the perimeter light is not blinding but the hazards are. Nice and gets peoples attention when overtaking on inclement weather.

Had led bulbs before I switched to the new amber white switchback led bulbs and these are even brighter. Looks good too

These lights are definitely the best turn signal lights you can purchase, very high quality, you can feel the quality just by touching them, and when you have them on you are always the brightest on the street, the yellow led are strong as the emergency vehicles lights.The white led provides an elegant and completes the look of your vehicle at night.

Installed these a few weeks ago and they are the only ones to work without a resister...and they work and look great. We will see how they work in the heat of summer but in the fall going into winter no overheating or issues!
