PREMATURE FAILURE WITH BUICK RANIER LED EYEBROW LIGHTS

When installing a low-load LED bulb replacement in 2004+ Chevrolet Colorado and GMC Canyon trucks you may run into a problem with the LED burning out or melting. This happens because when the truck first starts up the alternator (which is controlled by computer) is pushing out more than 14 vdc, maybe 15.5 or 16 vdc. If this happens multiple times over the course of several days the LED daytime running light bulbs can get damaged.

D1S and D2S LED Headlight Bulb Replacements - Are they brighter than HID?

Many vehicles that roll off the dealership lot come equipped with HID Projector headlights. While we are looking at a unit for a Nissan 350Z, the same information can be applied to a variety of cars. A Chevrolet Silverado with HID headlights, GMC Sierra, a Ford F-150, or a new Chevy Camaro, that came with factory xenon or HID headlights will use something called a D Series bulb.

But what is a D Series bulb? They come in D1, D2, D3, and D4 variants. The new ones are produced without any mercury in them, making them more environmentally friendly. In terms of installing LED bulbs, there are D1, D2, D3, and D4 bulbs that will work with the associating HID. The question is, are LED bulbs brighter than HID?
