Low beams for DRL?

I want to add DRL to my truck, but don't want to have the melting lens issue everyone talks about. I am also a cheap bastid. So I was thinking about rigging a standard bosch type relay ($3) to just jump the two contacts on the headlight switch whenever the ignition is on and the park brake is off. Has anyone done it already? Wondering how hard it is to access the wiring and if I am missing something that will get screwed up if I try this.

Yeah, my 09 Tacoma I have at work is fine too after 57K.

Wish we knew why some of them melt and some don't.

 

The Tacos never came with auto headlight on off feature but if you leave the headlight switch to the on position...they turn on the moment you turn the key and turn off the moment you remove the key and open the door. This is my DRL solution!

 

I've been doing that. What bothers me is the interior lights come on and the clock and compass/temp gauge dim. I find myself flipping the lights off and back on so I can see the temp or clock when driving during the day with the lights on.

I figured out how to make just the low beams come on automatically. To make it completely seamless would take 3 or 4 relays. Unless I can figure out how to use the factory drl signal from the body control module. Then it might be only two relays. But probably would have to buy the factory harness to plug into the BCU. At that point, may as well just spend the 60 bucks for the factory turn signal drl kit and pray the lenses don't melt.
