Premature Failure with Buick Ranier LED Eyebrow Lights

Mar 17th 2017

When installing a lowload LED bulb replacement in the Buick Rainier or similar vehicle, you may run into a problem with the LED burning out often with the headlight "Eyebrow" light accents. 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 bulbs can get damaged.
