Front Turn signals

We've all seen various ways to install front turn signals. Like many others, I wanted front signals without sacrificing parking lights while still having it appear stock. I found some cheapo generic sockets at NAPA that I managed to make fit without having to create any additional brackets. I did have to bore out the stock parking light hole (which was extremely painful, but necessary). The problem was I couldn't get the lens to fit back flush over a dual filament 6v bulb. As suggested on a previous 2A page thread, I ordered a pair of 6V LED bulbs from superbrightleds.com that have a slightly shorter length. They are just short enough that the lens and bezel fit as they should. I'm still chasing some wiring gremlins to get everything blinking in the correct places at the correct times but the physical fit works pretty well.

Very cool Ryan!

One one of our work trucks, the old rear incandescent bulbs burned so we replaced them with LEDs. That caused the blinkers to blink really fast like the flasher was bad. So I had to swap them back to incandescent. That might be what you have going on.

Looks like you are onto something Nate. I just put the incandescent bulbs back in and everything blinks as it should.  In addition to flasher oddities, with the LED's installed the parking lights come on with the headlights. With the incandescent bulbs installed, the parking lights turn off when the headlights are on just like they are supposed to. Why would the LED lights make a difference?

I may be modifying the light sockets to accommodate incandescent bulbs after all.

Your guess it as good as mine. LEDs are kinda strange like that. I wired my headlight switch so the parking lights stay on with the headlights. LEDs would be nice, but they seem like more of a pain than it is worth.

Nicely done Ryan!!   I like that better than my approach.  By the way, I'd lend you my tractor anytime you would need it, as long as I could get free rides in that Willys of yours.

This LED idea is definitely a bust. I would delete the entire thread but I suppose I'll leave it up here to save anyone else from trying it. Besides, it also contains a written offer from Tim that I get to use his tractor   Grin

If I was to take a WAG, I would say that the LEDs are drawing more or less, probably less, power than the regular bulb uses. Somehow, this is screwing up the flasher. I haven't the slightest idea as to how that works.

Ryan, since you have the stuff, try wiring both fronts to signal at the same time, kinda like 4-way emergencies. So if you say, signal right, both will come on and flash. I bet the problem will go away. I know the 4 ways worked fine on our truck with the LEDs.

There are ways to fix the LED lighting, You'll just have to dig a littl deeper.. I am thinking it involves adding a resistor to the circuit which would be easy to hide. but as for what ohm  value of it I dunno.

I'd keep after it as those LED light should last as long as the jeep now.

I'd try and help look it up in the net for ya but I gotta get to work shoveling the snow off my escort truck here in Wray, Colorado this AM...

And the problem in a a nutshell is they draw way too little juice.  You either have to use a flasher wired for them or add a load to make the flasher think they are regular bulbs. As far as them lighting up with the headlights, they may actually be lighting up on stray current, you HL switch may be a little dirty inside.

I have heard of guys adding a regular bulb in series to make them work but that would be backwards to me, It would be a good troubleshooting method tho..

To remedy the fast blinking LED's, go get an electronic flasher at any auto store

Here's an interesting page about it.:

If you do come up with a solution that works well in the 3A,please let us know, as this is a great thread to put in a FAQ file for those who are adding turn signals.  Cheesy

Led draws way less than a reg bulb.
You could use a small resistor, to make up the difference.

I struck out today trying to find either a 6V electric flasher or the right size resistors locally. If I do replace the flasher I will undoubtedly have to upgrade the rear lights to LED's too. Not sure I want to chase the problem that far. It's looking like modifying the front sockets again to fit the regular bulbs will be an easier task with a more guaranteed outcome.

Regardless, the over drive unit has arrived from my new friend Herm so that'll be the main project for the rest of the weekend.

Ryan, I made spacers to space out the lenses on my '53. You could make some sort of spacer on a lathe if you have one or know someone with one. That is what I want to do eventually with aluminum.

I made 8 of these on a plasma cam, 4 per side. Each were an 1/8" thick.

Does anyone know where I can find a 6V electronic flasher with only 3 terminals? My current thermal flasher (32CP-MAX6) has three terminals marked "P", "L", and "X". Because I followed the instructions when I bought the turn signal, I know how and why these terminals connect to the wires on my Jeep. Beyond that, I'm lost.

I was hoping to find a new 6V flasher for my LED's with the same terminal configuration so I could just plug it in and go. The only 6V elec flasher I have been able to find (online or otherwise) has 5 terminals. The terminals are marked "30", "85", "86", "87", and "87a".

I've tried every conceivable combination of connecting my three wires to these 5 terminals and can't get it to work (yes, I know electrical experimentation can make things go "poof") . I'm not even sure if this flasher can be made to work or if it is completely incompatible.

I put LED's in the tail lights as well as the parking light/turn signals in order to rules out any inconsistencies with different bulbs.

If anyone has a source for three terminal 6V electronic flashers or suggestions on how I can make use of my 5 terminal one please let me know. Thanks.
