Sylvania 35069 LEDriving Pipe DRL/Accent Light KitThese use a light pipe (similar to Energizer's new Fusion brand of camping flashlights) to transmit light, along with white LEDs that are advertised as 6200K color temperature. I found that is a very bright and white light, with no hint of green, blue, purple, or yellow. In broad daylight, the lights are extremely bright to look at directly and seem even brighter than HID headlights in that test scenario.The driver module connects directly to the vehicle battery system, without the need for external relays. The only tap that is optional is the feed to the parking lights which dims the DRLs. I honestly don't feel it is necessary as having the full LED brightness would augment night driving capabilities although some people might be bothered by the white light. The same people that complain about how the "bluish bright lights" bother their eyes would probably complain about these at full brightness in the dark. The driver module detects when the voltage goes over a certain threshold indicating the alternator is spinning, which is quite intelligent and convenient.The only complaint I have is with the long shape of the DRLs making it difficult to install on most modern cars. I struggled to find a suitable location on a Mustang, Cobalt, etc... but there are plenty of spaces on older Fords especially trucks/vans. Even with an empty space, the kit does not include mounting brackets that are usually required to bolt the lights to the bumper or a suitable metal surface. You have to get creative with the actual mounting.The good news is that many late model cars already use LED DRLs and LED foglights, some even have LED headlights as far back as 6-7 years ago. The light pipe LED DRL differs from Sylvania's "pixelated" LED DRLs by how the LED DRLs look. Most OEM LED DRL solutions are of the pixelated design, ala Audi or Kia.Overall: 4/5 stars. Mounting options are rather limited on newer cars, you have to get creative. In addition, the lack of generic L-brackets or brackets hampers installation out of the box. I had to go out to the hardware store and get creative.
