ok, here's the problem.  i'm building a hot rod i'm using a column by flaming river and a wiring kit from keep it clean.  For the rear tail lights i have three wires from the kit, brake, turn, and running.  the problem is i only have 2 wires on the led tailights running and brake.  So how can i build a relay to flash the high intensity side along with the keeping the brake function?  The wire kit already has a flasher built in, will this one work or do i need an electronic one?

If your parking lights were on all of the time, such as on a motorcycle, since you probably do not ride with your parking lights on in the daytime, this may take a couple relays.  I can draw you a diagram tonight.

At the bottom of this page is how it is done if parking lights are on all the time, there will ba an additional wire on this relay and an additional relay in your diagram.  you would also need to substitute brake wire of your vehicle where it says parking light hot on the diagram.  Which light do you want to use as the blinker, the running light or the brake light?  Are you  using the brighter of the 2 as the brake light?

Any Luck?

seems to work fine although i haven't tested the turn signal since the column is not wired up, but i was thinking if i have standard bulbs in the front then when i use the turn lights they will flash opposite times from eachother.  unless i use a similar relay for the front lights as well.

What would be the concern of timing if the car that needs the info can only see one set of the lights?

ok, i hooked up the column here's what i get, when haz are on i get solid lights, when brake is pressed the and i activate the turn signal the light shuts off, and when i activate the turn signal with no brake nothing happens.  I'm getting no flash from the flasher.  Is this because the relay setup draws to little currents to make the flasher flash.  Maybe load resistor might help?  I thought they were only for hyper flash or burnt bulb indicator.   Any suggestions.

I missed your question in the initial post about, will need to get a different flasher. Yes you may need to get a solid state flasher. The resistor will work, the only thing there is the extra heat, you will have to mount it to a heat sink of some sort.

Your easiest out will be the new flasher. Sorry I missed that.

so the relay config is correct, the only thing that seems wierd is when i activate the turn signals i get no light shouldn't they come on but not flash

You did notice the black text in the picture and connected the missing wire described by the text? I have looked it over again and it all looks in order. But yes I too would think that they should remain on any time the blinker is on. Make sure that there is constant voltage on the center relay.

Ok the reason i had no lights when i used the signal was because the key has to be on.  OOPS.  Any ways i bought some electronic flashers and the signals work great all seems to be perfect except when i plug in the column i loose the brake lights they will flash for just a second, when the column is unpluged they stay on..  on the column it has a wire for brake switch not sure why.  any ideas?

The Brake wire on the column is to make sure you can not put the vehicle in gear without applying the brake. Is the shifter on the column? Do you have to apply the brake to shift from park?

It seems as though the brake switch can not provide enough current to run the lights and the shifter solenoid. Could this be the case?

i do not need to apply the brake when shifting.  i'm using a relay, but the supply (87) is wired to the brake switch supply wire.  should i disconnect the wire from the column since i don't seem to need it?

If it will shift out of park without the brake being applied, I have no idea why it is even on the column. Is the shifter on the column? If not on yours, is it available with the shifter on the column? If it is serving no purpose, I see no reason to keep it in the loop. Call the manufacturer and see why it is there.
