Awesome pics gspup, thanks for posting! What trail(s) are that in Moab? The first one looks like the entrance to Kane Creek?
As far as the wiring of the 3/4" LEDs, sorry about the issue. Unfortunately to date, nobody makes a small light of this size that is dual function of a marker *and* turn signal. However, a small wiring modification can be done to make these lights dual function. I will explain how to do it but to help understand, I'll explain the issue as to why they cannot work as a dual function:
At first it seems possible, there are 2 lights leading to the side marker light, as well as 2 wires on the LED. However, the way the OEM wires work, they reverse polarity depending on if the parking lights are turned on or not. You will notice this by observing the way the front mounted parking/turn signals work compared to the side markers. With the parking lights off, the 2 lights will flash opposite of each other. In other words, when one is on, the other is off during the blinking. However, with the parking lights on, they will blink in unison.
The problem this presents with the LEDs are that an LED is polarity sensative. Meaning, the LED will only work with electricity flowing in 1 direction. The OEM light uses an incandescent bulb, which will light up no matter which direction electricity is flowing through it.
So to make the LEDs work, they must recieve electricity in 1 direction only no matter if the parking lights are on or off. This can be done with a wiring modification:
Find out which wire supplies power for the parking light function, and which one supplies the turn signal function. The parking light
wire needs a 560 Ohm resistor. (This will make the parking light feature power the LED to ~1/2 - ~2/3 intensity, which is still very bright and is easily seen in the daylight) Then, both of the wires get a rectifier diode installed. The rectifier diodes allow lectricity to flow in only 1 direction. After the rectifier diodes, the parking and blinker wires get joined together to make a single "+" wire going to the LED. The rectifier diodes prevent one function from backfeeding the other function. Then, a ground wire needs to be ran from the "-" side of the LED to a ground. I've seen the best luck with this wire tapping into the Jeep's common ground wire for the front facing turn signal.
With the above modification, the 3/4" diameter LED will act as both a turn signal and parking light. The cost for all the parts is $5 or less, unfortunately it is just a matter of being comfortable with doing it and having access to a soldering iron. It is not a hard task though and I have not heard of any person messing anything up if done wrong, the lights just simply wont work right. A couple years ago when experimenting around with this, we installed wires in about every way possible before finding this out, and there was no damage to the wiring system. So if it's your first time with wiring, you'll be fine.
Also, here is a good write up I found on this forum with part numbers: http://www.jeepforum.com/forum/f9/2-...ite-up-933239/
This gentleman made a circuit board but it can also be done in-line with the wires.
Until I can find a supplier to make these little wiring harnesses, unfortunately the DIY way is the only one to get the 3/4" LEDs to work as a dual function.
- glad you got 'em working! I've been fooled by a fuse with only a hairline break before, so good advice about checking again.
