any chance you bought the wrong bulbs and switch the wires to make it work?? Can you guys post the bulb # thats not working?

Did you order 1156-X45-T? If not, that's what I would recommend for signal light.

Liscence Plate 2 @ BA9S-W4-12V - worked fine
Front Side Marker 2 @ WLED-NW6 - worked fine
Rear Side Marker 2 @ WLED-NW6 - worked fine
Dome light 1 @ 1156-CW18-T - worked fine
Reverse Light 1 @ 1156-CW45-T - worked fine

These are what I ordered for the front lamps - got the numbers from searching on the forum. I tried each bulb and each didn't work in the front.

Front Parking 2 @ 67-A9-WV
Front Signal 2 @ 1156-A24-WV

I haven't played around with it since last week. Had a trip to RC and had other more important items to get done. Once I have a moment I'll play around with it.

I can't tell you if those will work because I got these for front signal and marker and they're the cat's pajamas: http://www.superbrightleds.com/cgi-b...115x-x45-T.htm

So, now I tried to hook up the trailer and...nothing. I have confirmed that the trailer lights are not the problem, it's the load from the LEDs all around. Any ideas on how to get the trailer lights to work with LEDs all around the truck, except the trailer?

Chris, are you using the factory trailer connection? Are you getting 12v at all the proper leads? Are you using an LED flasher?
I'm just wondering if your trailer lights are getting 0 or limited power and/or if there is an issue with reversed polarity due to the truck LEDs.

I am using an LED compatible flasher with LEDs all around the truck, including load reducers up front. Truck light works great.

As for trailer, the factory harness is ROW 7 prong plug that I am using the special converter from AB or RN to 4 prong. When I test plug, While right flasher is on, I seem to get 10 volts from right flasher and a few volts from left flasher?... Without the trailer hooked up, the lights on truck work properly. However, when I hook up trailer, i get nothing from trailer and right flasher on truck is weak and I get a some faint flasher light coming from left flasher.

Very odd.

It's probably a grounding issue. As I'm sure you are aware the white wire from the flat four is grounded on the trailer chassis and is also grounded on the tow vehicle. Be sure the connection is clean and tight.

I'm thinking that the LED electronic flasher can not power more than the lights on the truck.

Maybe the solution is to put load resistors on the rear truck flashers, as i did with the front, and go with the original stock relay rather than the LED compatible relay that I am currently running.

Maybe just put leds bulbs on the trailer.

I recently installed an EP26 4 prong LED compatible flasher relay with LEDs indicators all around. With this setup, I get no flash...no sound...nothing.


However, riddle me this...

When I install one load resistor on one of the two front LED indictors...all indicator signals work as they should. Except for the dash indicator light, for the side without the load resistor, doesn't flash at all...but the dash light on the same side as the LED flasher works properly?...

Nevertheless, when I install a load resistor on each of the front indicators, along with the EP26 LED flasher installed...everything works perfectly. i just hope the trailer lights work with this new 4 prong relay?...this is the point of my endless battle with this electrical issue.

Whatever the case, shouldn't an LED flasher work with LEDs indicators all around, no matter the load draw?... Isn't this the purpose of the LED flasher relay?...

Actually no, or I should say it depends upon which vehicle and lights it was designed for. The flasher works by comparing the load from one side to the other with a resistor hoop. So even though you may have an led compatible flasher relay, it still wants to see a certain load in order to work properly.

Yes, an LED compatible EP26 should work regardless of load impedance.

On that note, even a NON-LED compatible EP26 should work regardless of load impedance You will just get fast flashes with the LED sans load resistors.

Have you tried testing the EP26 by wire wrapping on the pins? There is a possibility you have a bad one. The first EP26 I bought from Advance auto didn't work properly (it would light up the turn signal constantly). I diagnosed my entire truck's wiring front to back 3x and everything looked right. I pulled the relay out, wire-wrapped to test, replicated the problem with a single light, emailed Tridon, and they emailed me back saying based on my results it was not working properly. I bought a second EP26 and voila, it worked as necessary.

Just saying that these flashers seem to be made very badly made and QC seems to be the worst I have ever seen for solid state circuitry. Wasted a lot of my time trying to track down what was wrong when it was just a bad part off the assembly line.

I thought I would post some pics to help in understanding this Led issue.
As you can see the relay on the left is the oem thermal flasher. The other three are commonly available led compatible electronic flashers. Obviously, they all appear quite different including the three led compatible ones. All have one thing in common, they require the proper resistance to provide the correct operation of the turn signal lights. Interesting enough, you can modify the oem thermal relay by carefully removing material from the resitor hoops ( shown in the second photo). It has to be done slowly and checked in order to get to the proper resistance.

I have a query. I have had LED lights all around on my 1995 D90 SW since the big group buy I believe in 2006. LED flasher, brakes lights, reverse light and front and rear signal lights. No resistors installed. Only ill effect is I had to remove the trafficator light in the dash for the signals to blink properly. What can I do to get the trafficator light to work?

I ran into this when recently installed LED lights on a guys 1995 ST. He got the lights from Safaridust and I did the install just as I had done successfully on my truck. When the signal lights blinked oddly, I began to search and found that I had to install resistors on the fromt signals? I took mine out and checked because I did not recall having done that on my truck and sure enough no resistors. I re-installed his factory front siganls and re-installed his traffictor light and all is well.

Thanks!

Troy

You could try an led trafficator light. It might work. You could also try using load resistors. It's all about how the flasher relay is sensing the load and how its configured.

From what I can tell from the Superbrights website. The LED trafficator bulb I need to replace the clear factory bulb is the 74-x in Cool White. Can anyone confrim that please?

Thanks!

Update:

With the stock trafficator bulb - all the turn signals blink and the trafficator is very dim.

With LED bulb 74-G, trafficator will only blink on one side or the other. Bag sad it was polarized. So I flipped the bulb in the socket and it works the opposite side.

Thoughts anyone?

Troy, just swap your front turns for the old incandescents and see what happens.
