How to Install a Daytime Running Light Switch

One of the most annoying things that will happen to you when you are driving is when any of your vehicle lights start to wear out. Sometimes, this is caused by having old, busted lights. But most of the time, it is usually due to a worn out switch. When this happens, it is important to replace the switch as soon as possible. This is to keep you safe and secured when driving in dark areas. Among your vehicle light switches that wear out faster than the others is the daytime running light switch. It powers the lights in from of your vehicle when it is moving forward. When these lights die, it can be easily replaced with new ones. When the switch wears out, here's how you can replace a daylight running light switch at home.

Difficulty level: Moderate

What you'll need:

  • Pliers
  • Replacement daylight running light switch

Step 1: Check the condition of your old daytime light switch. Look for signs of corrosion and rusting.

Step 2: Fit the light switch close to the battery under the bonnet, either from the battery main posts or from a fused live lead near it.

Step 3: The black wire is the earth lead, while the red wire should have an ignition feed that should only live when the ignition is on.

Step 4: Connect the earth lead to the closest earth point. You can fit an in-line 5-amp fuse that you can buy from an auto parts store for safety. It has a third lead that you need to connect to the dipped headlights of your vehicle. It should also extinguish the LEDs when the headlights are used.

Step 5: The actual wiring of the control unit to the two daytime running lights is simple. You need to fit them in front of the car, in its correct position. Feed the wires down to the bumper from under the bonnet, and select a spot on each side where you can screw the lights.

Step 6: Piggyback and fuse off the fan motor fuse, which is usually 10 amperes. Connect the remaining wire or relay to the headlamp low beam feed.

Step 7: Check if the daytime running lights are running if they turn on when you start the engine, and turn off when you turn on the headlights.

And just like that, your daytime running light switch is as good as new. You can finish installing your replacement switch in about an hour or so, depending on your familiarity on working with wires. It is important that you dispose your old switch and avoid from reusing it. Using an old switch in your vehicle would only worsen the problem since it already has issues like rusting and corrosion. Once replaced, check your switch once in a while if it has signs of wearing out. Replace it immediately to keep it from leaving your daytime running lights dim or dead. Do this to the other lights of your vehicle as well, such as headlights and taillights.
