Description
Since the 4-headlight system was introduced in 1988 on GM pickups and suburbans, owners of these vehicles have wondered why their low beams go off when the high beams are turned on? No good reason we can think of. Increase the intensity and improve the spread pattern by keeping all four lights on when in high beam mode. Easy 10 minute installation. *Note: For all 1988-98 GM trucks including trucks with low beam daytime running lights. Slight modifications may be necessary for some vehicles such as 88-91 Suburbans.
