You can ground the marker light brown wire and run a relay off the blue turn wire that would cut the flow on the marker light as the light flashes on.

They need to come on with the parking lights. Let me work on this. Later this afternoon I am going to do a mock up and see what I can figure out.

Well the LED I had I thought was a dual park/turn lamp is just single park lamp so forget that project, sorry dude, I don't have the answer. All I know for sure is that you can run LED's in the side markers and it will not affect the functions.

well i tried the led side markers today with regular front parklights..... and one fried. i think it was a dud but maybe it fried cuz the parklights were higher resistance?? so the leds were gettin too much current? idk hopefully its just that its a pos from china. im not havin good luck with all of this....

We ran them on the trucks bumper poles at work so a few fell into my pocket since I was the mechanic, lol. I guess it was about a month ago I installed the side marker lenses MrClean hooked me up with and one of the bulbs blew so I stuck a LED 198 in and it's been fine so far.

I'll think on this... It's an interesting dilemma.

I spent all day looking on the net for answers, that is the best I can find. I tried to do a mock up off that relay shown but my solder gun is acting like an *******. I did find an LED combo park/turn bulb in the garage from my GMT400. I did confirm that it will not work off a stock flasher unit. Not enough "drain" to activate it. I got to get Old77 in here, he added LED's to his newer Burb, but I think it was taillights. He may not have dealt with the alternating flash issue, he may know who has an answer.

That diagram pic from that site must have some kind of copywrite program on it. When I try to download it I get a fuggin sex spam, and when I repost here it is very hard to read.

When put my LED tails on my burb (a 2007) I wired a set of resistors in for each light to prevent what is commonly called Hyperflash. What are you meaning by "alternating flash issue"?

We are trying to figure out how to run LED's in the front turns and front side markers. LED's may screw up the alternating flash they have from factory setup, know what I mean G?
