I have a grill hanging on the wall in the garage from an early bronco. Been meaning to wire up some headlights and turn signals. Whats the best way to do this so I can turn them on and off when I want to, and also make it so that the turn signals flash too. Thanks

Using real headlights will require a big power supply. Find some composite conversion housings and mount taillight bulbs in them. Or carefully break a hole in the back of real headlight bulbs and mount a taillight bulb in there.
To make the blinkers flash go buy a solid state universal flasher. Its more expensive than the standard thermal flashers but the normal ones will drive you insane with the clicking noise.

Use a computer power supply to run it. You can either mount a switch on the power supply or mount 2 switches. 1 for headlights and one for blinkers.

Or maybe get some inexpensive H4 e-code conversions and adapt a different bulb to the P45T mounting hole.

This is the best answer. You probably only need a 10 to 15 watt lamp in there anyway. Turn signal bulbs are typically five watts. Figure two headlights (15 watts) are going to be about 3 amps, and two turn signals will be about 1.5 amps (all are rounded up for a safety factor) says a five amp 12 volt power supply (think one of those things that are used to power CB radios) would be adequate.

Stock headlights are 55 watts each, so two would draw almost 10 amps. That's a lot of power, and they'd be really bright.
