need wiring help for roof clearance lights

you may remember a few months back i posted about putting clearance lights from a truck on my ZJ. i ended up taking them off because one became a projectile on the freeway, due to the cheap 2 sided tape i used to attach them. i want to put them back on (will be using silicone to attach them this time), but i want to do something a little different.

i want them to turn on with the running lights, easy enough. just a relay with the trigger from the pass. side marker light. but heres the catch. when i turn on the hazards, i want the 2 outside clearance lights to flash with them. how would i wire this? i know im gonna need a few relays at least. not super experienced with wiring, i can usually figure my way around it, but this has got me stumped. can you explain it to me? if someone could make up a schematic, that would be even better. thanks

What you need is this right here- http://www.thehitchstore.com/3-to-2-...er-p-1705.html

Properly wired, this will do exactly what you are describing. Pretty easy to wire up with the instructions or a quick Google search.

Yes but the ones you have labeled "from hazard" will technically come "from turn signal" on each side. Same wire, but just throwing that out there.

You got it boss.

edit- just so you're aware, any way you do this- those clearance lights will now also act as turn signals. If you ONLY want them both to come on when you turn your hazards on and NOT the individual turn signals, you will need to do a bit more wiring and probably will require the use of some sort of logic board so as to not supply voltage unless both 'inputs' have 12 volts. Ya know?

I only want them to flash when the hazards are turned on. Do the hazards work off the same relay as the turn signals, or is there a separate relay? If they're separate, I could run the "from hazard" wires from the hazard relay itself, instead of from the flasher bulbs?

So I might be wrong, but if you wire them as running lights and turn on your lights in the city, you're going to get pulled over faster then any other as you're only allowed 4 lights (driving lights, excludes orange lights like on semi's on the roof) in front when on city/state roads. Offroad lights would fall under this category as they are for "offroad use only" and are not street legal.

I could be reading what you wrote wrong, but last thing you want is DPS tagging you for that, you know as well as I do they'll bend you over for something like that.

You misunderstood. I am talking about the amber lights on the roof like big trucks have.
