Summary:<\/strong> On the Chevy Malibu and other GM vehicles when the high-beam headlamps are engaged the low-beam headlamps automatically turn off. I found this absurd because I wanted to be able to have my headlamps produce as much light as they are capable of. The high-beam and low-beam lamps are in separate chambers and I see no reason why the low beams should turn off just because the high beams are engaged. This mod makes it possible. Driving with the high beams only illuminates the area ahead of you, the low beams illuminate the area just in front of you, but with this mod, you can enjoy the best of both.<\/p>\n

Malibu headlight electrical theory:<\/strong>
\nThe Malibu headlamps are controlled ground side. When the headlamps are not illuminating, there is 12V+ applied to both terminals. To turn a headlamp “on” and make it illuminate you must switch one of those terminals to ground. Bizarre? It gives me a headache to think backward, but after a while, it beings to make sense.<\/p>\n

Under a stock configuration the headlights will work as follows:
\nLow beam:
\nBlue<\/span> wire \u2013 at resting state \u201coff\u201d is 12V+, drops to ground when turned \u201con\u201d
\nOrange<\/span> wire \u2013 remains at 12V+ constantly<\/p>\n

High beam:
\nPink<\/span> wire \u2013 at rest \u201coff\u201d is 12V+, drops to ground when turned \u201con\u201d
\nOrange<\/span> wire – remains at 12V+ constantly<\/p>\n

So if we want the low beam lamps to stay on when the high beam lamps are engaged we need to drop one of those low beam terminals to ground (blue wire). In this mod the relay does that for us.<\/span><\/p>\n
