Hi fellows
I bought some aftermarket headlights on ebay. The ones with the halos and led turn signals as seen here: http://cgi.ebay.com/ebaymotors/97-04-Dodge-Dakota-Durango-LED-CCFL-Halo-Headlights-BK_W0QQcmdZViewItemQQ_trkparmsZ65Q3a12Q7c66Q3a2Q7c 39Q3a1Q7c72Q3a2102Q7c240Q3a1318Q7c301Q3a1Q7c293Q3a 1Q7c294Q3a50QQ_trksidZp3286Q2ec0Q2em14QQhashZitem1 e57235dadQQitemZ130310954413QQptZMotorsQ5fCarQ5fTr uckQ5fPartsQ5fAccessories#ebayphotohosting

The quality of them is good and they are looking great. The only thing is that the turn signals are hyperflashing since there is one of the stock bulb being replaced by 5 LEDs. I know that I have to wire in a resistor to get rid of this. So far I have tried several different locations but I can't get it to work, not even with the help of a local electronics guru.

Can anybody help me out in this matter by providing what kind of resistor I need and how to wire it up?

Thanks a lot for your help. Cheers from switzerland

i had the fast flash when i put LED's in mine, front & back.... along the troubleshooting process i picked up another flasher relay from vatozone & swapped it out. it worked for some reason... flashing was back to normal.

may be worth a shot to avoid fucking around with a resistor....

For a 2002 you'll need one of these

If you're not going to have LED's on the rear (Tail lights) I would go with the 6 OHM. 3 OHM if you decide to have LED's on the rear and front. Search around you might find them cheaper.

hi guys, thanks a lot for your input. finally using 2x 3 ohm resistors got them to work properly. I wired them up as shown in above digagram so if any of you guys are having the same problem this is the solution to it. I used 3ohm because I also got matching LED tail lights. For non LED taillights use 6 ohm as per diagram...

cheers

I also had this problem, with full led's front and back. I swapped out the flasher relay with an electronic one. The stock one measures the resistance in the line, so when you blow a bulb you know since it flashes fast. I have heard there is some concern with adding more resistance since the resistors can get real hot. I'd just make sure your resistors don't get too hot by checking them after running the flashers for awhile. Also, the relay is much easier to replace, just plug it in. Sorry, but I don't remember where I got the electronic one, think i just googled "electronic flasher relay". The web site I bought it from had diagrams with the pin layouts and measurements, but not by year and make/model. It was pretty easy to figure out which one it was, though.

That only works on the '98-2000 trucks.

I did not know that. Do you know why it doesn't work on newer trucks?
