How to disable drl's?

Southeast Toyota says dealers know how to disable DRL's; but my dealer claims they do not? Apparently, this is NOT a federally mandated safety requirement: but manufacturer choice?

On verge of joining sheriff's reserve and among other things want to disable DRL's for daytime suspect/fugitive searches. Originally wanted aftermarket exhaust for more power and better sound: but not want to keep stock, as it's so quiet.

Presume it entails going into computer somewhere to disableand canit be done with handheld device at dealer?

Any help greatly appreciated!

Re: How to disable drl's?

You need to do a search on the threads for "how to disable DRL's" and you will find a bunch of info on how to do that in great detail with pics. The dealer wont do it for you as they consider it a safety issue and in case your in an accident dont want the potential liability....its a legal thing.

I'm with you in that I hated my DRL's and disconnected mine with the "snipping the small blue wire" method and it worked great with no residual effects on anything else. You'll see what I'm referring to when you do your search. There are other methods in the threads but some caution that they can cause excessive heating up of a certain resister in the headlight circuit. Once again you will see that too once you do the reseach and you just need to decide which method is for you.

One of the many reasons why I wanted them off was because I changed my bulbs to Sylvania Brightstar and I didnt want them on all the time (even with less power). Good luck in your search.

I tried using search Zeke and window didn't come up to state search parameters? Hopefully "mom's" will?

Thank you both!

Don't bother cutting anything... There's a 2"x3" aluminum-clad resistor behind the grill below the driver's side headlight. The connector for it is right above it attached to the radiator support. Just unplug it. It has a retaining latch that you just press on to unplug, and it's an extremely tight fit for large hands, but work at it and you'll get it. The latch is on the plug, on the harness side. The DRL's seek ground through that resistor when you turn the key on. The resistor limits that ground, that's why they are dimmer than with the normal headlight function. You're just eliminating that ground. Don't remove the fuse or relay or your headlights won't work. The DRL fuse powers the DRL relay coil. The DRL relay supplies full ground to the headlights when the headlights are turned on.

Just unplug it. Very easy. I have unplugged many on the trail before night runs.

Someone, somewhere, somehow will complicate this somewhat.

True story. I'm not good at names and it was dark, but I'm pretty sure Tatem's the one that unplugged my DRLs on the Saturday night run at WTF 2011. It's easy if you can squeeze your hand in there.
