Chevrolet Sail 3, Change The Tail Light Circuit, Make It Be Double Tail Light At Day Time, Double Driving Light At Night.

The circuit like the picture shown above, find the driving light circuit, series connect the 1N5408 diode, and then find the tail light circuit, parallel connect a line out, ,make this line to parallel connect one of 1n5408 diode on the series connection circuit, finally connect this line on the driving line circuit, then we achieve the work. 1n5408 diode, the maximum current is 3A, reverse voltage is 1000V, drop to about 0.5V. Under this situation, at the day time, while we don’t open the sidemarker light, the rear driving light and tail light could be used as tail light both. At the night time, while we open the sidemarker light, it will be restored to the function as original, the driving light will be driving light again, we can take full advantage of the tail light of Sail 3.
