Where else can daytime running lights be connected besides ACC?

Daytime running lights can be connected to other locations in the front of the vehicle besides the ACC line, but when determining the location, areas with high temperatures and prone to water accumulation should be avoided as much as possible. Below is more information about daytime running lights: 1. Daytime running lights are lamps installed at the front of the vehicle to make it more easily recognizable during daytime driving. These lights are not for the driver to see the road clearly but to signal others that a vehicle is approaching. 2. The power consumption of daytime running lights is only 13.5W. The luminous flux of the product is 70-90LM, with a color temperature range of 6000K-6700K, which is brighter than traditional halogen lights but consumes only 20% of the power of halogen headlights. 3. Daytime running lights must meet basic brightness requirements but should not be too bright to avoid disturbing others.

I often modify car lights myself. For daytime running lights (DRLs), besides connecting to the ACC, they can also be connected to the IGN ignition line, which only powers up when the engine starts. This better matches the original design intent of DRLs and avoids wasting electricity when parked. Directly connecting to the battery positive terminal is also an option, but you must add a relay and switch to control the circuit; otherwise, the lights will stay on and drain the battery, which is very dangerous. The fuse box is another good choice—find a fuse slot that only powers up during ignition, such as the IGN or fuel pump fuse socket. When modifying, always insulate the connections with electrical tape and refer to the vehicle manual to check wiring diagrams. Avoid using incorrect wire sizes to prevent overheating and short circuits. Test the power supply before starting to ensure it responds correctly. This way, the modification is both cost-effective and safe, usually costing just around a hundred bucks.

For daytime running light safety, connecting to the IGN power source is most recommended. This position only supplies power when the engine is running, making it more reliable than ACC and avoiding unnecessary power consumption. If considering other options, connecting to the battery is feasible but requires an additional module to control the switch, as many regulations require lights to be on only while driving. Be cautious with modifications; choose the IGN fuse position in the fuse box, ensure the circuit is secure and not loose to reduce fire risks. It's best to prioritize compliance with local traffic regulations to avoid fines or accidents. DIY operations aren't complex—use a multimeter to check voltage before starting, and don't cut corners by directly connecting to incorrect lines.

Last time I modified the daytime running lights, I connected them to the IGN, which worked great—the lights only turn on when driving. Besides ACC, connecting to the battery is also an option but more troublesome, requiring an additional switch and relay for control. Some people connect them to the fuel pump fuse position, where power is only available when the engine is running, making it simpler. Just remember not to connect to a constant power source, or the battery may drain easily. As long as the wiring is properly insulated, there shouldn’t be any issues.
