Lighting Mod Question

I have a 2015 TRD, I am looking for a mod so my signal lights in the mirrors are on with the DRL's but not at full power so they will still blink with the turn signal. Anyone have any ideas besides direct wiring them into the DRL's.

 

Do the lights have two filiments or levels of brightness? If so, you could tap the low level wire to have 12v when drl's are on and then they should opperate as normal for a turn signal. If not, you would have to wire them to be on all the time a switch the flasher relay to turn them off when signaling instead of on. That might cause them to alternate with the other lights though.
I would first find out what bulb is in there.

 

ok cool, I don't think they are dual filament they are only on when you have your turn signals on or 4 ways flashing.
