How to make DRL lights come on with unlock?
I want to make my DRL lights or Headlights come on when i unlock my car ( so with my dome light) my DRL lights are connected to my side lights so i'd need to have my side lights on when i'm driving.
Any advice on how to do this would be great
Its a Ford Mondeo Mk 3 if thats any help.
It's a bit complicated as the interior light is on a dimmer.
If you can solder, quite easy:
You need a p-channel FET that can take the current drawn by the DRL
a FET has 3 leads,
source connect to 12v
gate connect to the interior light black/blue wire or GEM (connector 427 pin3 )
drain connect to the DRL
This should work for the DRL, if you want the headlights on as well, then feed into the headlight relay

On modern cars this is all controlled by the computer. If you can find someone who can do programming of the cars computer then you have a chance.
If not then you are stuck. Modern cars are not controlled like old cars.
- Why are my blink lights / brake lights working? I have a 72 Ford f100 and the rear left turn signal, brake ligh, hazard light isn't working. The light workings for "running lights " but does not blink or light up when I press the brake. I replaced the bulb. I don't know where to start
- 98 ford taurus stuck in gear tail lights won't come on? Everything was fine till I had a taillight out changed it it came on then started it wouldn't come out of gear and tail lights don't work
- 99 Ford ranger XLT base model. Park lights, dash lights, and license plates lights out I checked online and realized it was probably a fuse which it is. Fuse 11 in my power distribution box. The problem is I keep replacing at and soon as I turn on my lights it blows instantly. Have replaced it multiple times. So then I looked under my truck and disconnected the wiring to my taillights and replaced the fuse, it worked it didn't blow. Dash lights and license plates lights were on so I figured some where there's a problem with the brake lights. Any suggestions?
- Headlights, instrument cluster lights, tail lights, and dome light all stopped working at once? 1995 Mustang GT convertible, fuses are good, switch is good. I'm about to do a voltage drop test on it tomorrow but I wanted to see if you Ford guys knew something that I'm overlooking.
