How To Turn Off Daytime Running Lights

There are several ways to turn off the daytime running lamps. This is a general explanation on how to do so.

Turning off the daytime running lamps can be quite an easy task for anyone but, aside from being a detective or a private investigator there is no reason to disconnect them.

Car manufacturer have spent several millions of dollars to provide more safety devices to keep crashes and accidents down to a minimum.

Daytime Running Lamps have cut car-to-car accidents dramatically in recent years because you are more visible to other drivers, so diconnecting them shouldn't really be a consideration. If, however, you decide that they are bothersome for some reason here is a general guide to on how to turn them off.

Before entering the dark and confusing world of a vehicles electrical works, try this.

Turning off the daytime running lights on some vehicles (mostly the full-sized GM trucks) can be as simple as clicking the parking brake pedal just one or two clicks. This one or two clicks are enough to trip the switch that monitors the position of the pedal, but are not enough to put enough tension on the cable network running to the rear to actually engage the parking brake.

Tripping this switch may also trip the switch that lights the red "Brake" light in the dash. So this outcome may or may not be desirable, though many people drive their cars for thousands of miles with warning lights blaring and they simply ignore them. To some, an oil or coolant light - and a large repair bill - mean nothing to them.

If the red 'Brake' light comes on or clicking the pedal fails to turn off the light it's time to dive under the hood.

Under the hood there should be a fuse box, sometimes called a 'Power Distribution Box'.

Under the cover there will be fuses (some large and some small) and relays.

Check the underside of the cover or inside the owners manual for a 'map' to the box.

One of the relays should be labeled 'DRL' (Daytime Running Lamps), 'Daytime' or any variant.

Making sure the relay doesn't power any other devices, pulling this relay out will disconnect the DRLs.

If no relay is found, there should be a small "˜MINI' fuse in that same box. DRLs will not be run from a "˜MAXI' fuse.

If no fuse or relay is found under the hood it's time to look for an interior fuse panel.

The Owners Manual will tell you where it is. If you've lost it car makers have made it a literal Easter egg hunt these days.

Possible locations for the panel are:

Under the drivers side instrument panel.

In the drivers door jamb.

In the passengers door jamb.

In the drivers side 'kick panel'.

In the passengers 'kick panel'.

In the glove box.

In the center arm rest.

And, in very rare cases, the trunk.

The most common label for Daytime running lamps is 'DRL'. You have to watch out for a DRL related fuse or relay that also powers something else because manufactures can be tricky.

They don't want you to remove this valuable asset so they tend to put important things like A/C and power windows on the same circuit, but nothing that will result in a 'No start' or 'Blow up' condition.

Always check for the absence of other electrical accessories once you've removed a fuse or relay.
