guys, for example, the bulb says 55W input but gives a 100W output. should you consider getting relays and thicker bulb wires? yung iba kasi electrician sabi sakin no need since stock 55W ang input.
The most and effective way to determine the required fuse protection is to measure the actual amperes. Remove the fuse and insert the leads of the ammeter (ask from electrical shop) in place of the fuse. If the reading varies, then there is something wrong with your wiring. But if it stays constant, then probably you have to increase your fuse rating to next higher.
