Maybe somebody has delt with this before,....I dunno,....I'm trying to install a set of 2" marker LED's in my hood for the sidemarker/blinkers, but the problem is that I can only have one or the other, meaning, I'll have side markers only, or blinkers only,....I need both out of the same LED. There's only two wires, so that means there's only two ways to wire it up.

I was given this link saying that it may help me out, but I don't know anything about dealing with chips.

Chip link (http://www.newark.com/NewarkWebCommerce/newark/en_US/support/catalog/productDetail.jsp?id=34C7898)

I know that many of you all ain't into the bling-bling crap, but this is a daily driver and I need it to be as legal as it can be.

TIA

how did you get the rears to work??????

I am assuming that the LED you mention is in one of two states. ON or OFF. The question as I understand it is that you want it to be in an ON state as a marker. Thus power is applied when the running lights are ON and power is APPLIED when your head lights are ON. You also would like it to BLINK when you accuate the turn signal lever on the column. Am I following your question so far?

Rich,
I think since it has only 2 wires, that means that there is only one circuit. If you want this to work, you will need a 3 wire LED.

My rear 2" LED's are nothing more than marker's.

Yes, it's two wire lights, but Mesa 4x4 directed me to that chip in the link above and said that it would be a possiblity, I searched for a 2" LED that could be used for a side marker/blinker, but couldn't find any,....the only amber ones that I could find were 2x6,.....too big.

why dont you just drill a couple holes in the grill and run CJ markers/blinkers :flipoff2:

I am also having problems finding a 3 wire LED marker/blinker in a small size. :(

I dont know if this is going to make any sense, but here goes. A company called Lockhart Phillips makes a blinker kit for the rear of street bikes that integrates the blinkers into the brake lites. I dont know if this will help you out. FYI motorcycle brakes are a little different, they have off, on, and bright, so this might screw the whole process, but may give you another outlet for your LEDs all together. If you could find a crashed newer model street bike you could possibly use the break lites as your marker lites/turn signals. They also usually dont get effed up in a crash.

Just my .02
Good Luck

Why can't you just use the wires from your stock harness that powered the original side marker lights in your fender flares for the hood side marker lights? Aren't these 2-wires also? Or is it different on a TJ?

Yes, but they are both power wires, I think, anyway, those were the two wires that I was using.

Doc, I thought about that, I'm using 4" LED's for the front blinker and those will work just fine,.....it's the two inch side ones that I'm having problems with, I might just run them as night time lights and forget about the side blinkers.

dane, I'll look into that.

I agree with dane. Find the signal light intigrator for a zx9 or an r1 street bike because they have two rear tail lights from the factory. it will run you aroun 25 to 30 bucks on ebay. You could use the chip but you are pretty much building the intigrator from scratch and it will cost more money and time. Plus the intigrator comes with instructions and you can probably in an hour

You don't have to get the LP part, just go down to your local schucks and get a tail light integrator wiring kit for a trailer.

How can they both be power wires:question:
One has to be power and the other needs to be ground.
When you turn your lights on, the marker lights will come on. When you turn on your turn signals, they will flash off and on.
This is all integrated into your turn signal switch already. If you haven't already, you may need an electronic flasher unit, as the LEDs do not pull enough of a load to make the older flashers work.

The 2" led's I put in the hood have only two wires and they blink, I'll look and find out which wires I used. Let you know later. Mine is a TJ but the wiring couldn't be too far off.



edit: Sorry I thought you were running a YJ :D Below are the wires I use to put the LEDs in my hood. They blink and no special chips, gadgets, or integrater thingys were needed.

The brown wire and the black w/ yellow stripe wires in the wire harness.

Hook the brown wire to the blackwire on the LED.
Hook the black w/ yellow stripe wire to the white wire on the LED


Hope this helps.

I can ground the the LED to the frame of the Jeep and put the positive on either of the two side marker/blinker wires and get them to work.

As far as the flasher, I've already taken care of that for my rear LED's,....that's not the problem.

BackNBlackTJ, I'll give it a try and let you know.

You are making things way too complicated. Two wire LEDs will work fine as side markers using the stock wiring. Tail lights are more complicated only because of the need for a tail light and a brake/turn signal that needs to be brighter than the tails. The stock markers are only one circuit either on or off. The wiring harness and flasher circuit handle the flashing.

Here's the deal:

Stock wires for the sidemarker/turn signals

Gray
Black w/yellow

Stock wires for the front parking lights/turn signals

Gray
Black w/yellow
Black------this one went also to the stock fog lights.

All of these wires are "power" wires. I have no problem hooking up the 4" LED's as they are a three wire LED.

I just wanted to know if anybody had done the two inch LED's as side marker's and blinker's. The two inch LED only has two wires, a ground and a power,.....hooked one way into the stock harness, I have blinkers(headlights on or off),....hooked the other way, I have marker lights and blinkers (but only with the headlights on, I have nothing with the headlights off).

So, without spending anymore money than I have to, I'll probably just wire it up to blink with the headlights on,....and leave it at that.


Thanks for all the help.

Not for nuthin', but I think you need to get your hands on a wiring diagram. IIRC your front parking lights should be a 3-wire setup (park,turn,ground) (CJ is 2-wire since the housing grounds through the screws to the grill) and side markers should be 2-wire (park/turn, ground). The side markers stay on with the parking lights, then when you activate the turn signal, they flash alternately (not simultaneously) with the turn signals.

I do have a wiring diagram,.....none of the wires going to any of the parking lights are ground, at least, none that I can tell.

The front parking/turn signals have three wires, as I've said above, the side marker/turn signals have two wires.

The problem is not the wiring, but the LED's, the 2" LED's weren't designed to pull "double duty", I just wanted to know if anyone had pulled it off to where they used the 2" LED's as both side marker and blinker's.

The 2" led's I put in the hood have only two wires and they BLINK

Mine pull double duty... Works just fine.

The markers are ground, one wire is 12v and the other is ground that runs to the grill light chassis.

I hear what you're saying, but the factory side markers a 2-wire with a single element bulb as well. The 'logic' is in the circuitry as Robert indicated. Have you hooked the stockers back up to see what they do?

CJ/YJ's are housed in plastic. The light assembly is plastic, with a plastic plug. There is NO self ground. The wires are one ground, one positive. The lights blink on/off when the turn signal is used. Even if the lights are on. As was said the mechanism to do this is in the turn signal switch /flashers. Look @ the diagram above :rolleyes:


My TJ isn't here, but I bet it's the same. A simple on/off for the side markers. Do you at least have a test light?


I KNOW when Matt had to reatach side markers to compete in 2001 ProRock all he did was hook up a two wire light. I never saw them in action because He showed the vehicle I put on the stickers. (still do) One obstacle later they were usually gone.
