ComancheKid45 Posted March 25, 2016 Share Posted March 25, 2016 Alright fellas, if you happened to read the "lighting options" thread you would have seen the mention of Cree sealed beam LED headlights. Anyway I bought a set and went to install them this evening and noticed an issue. Here we go... When one side is installed along with a standard sealed beam on the other side the LED lights up fully on low beam, on high beam though it shuts off. With both LED lamps installed on low beam they both are bright on the top and the bottom 2 rows are very dim, and High beam is inoperable. So my question to you is, what's up? Haha. It's a stock non relay upgraded headlight harness and I even tried it out on my 96 XJ to see if it was a renix era issue with the same results. Just interested in opinions or options before i take action to possibly return them. Thanks for any info! Quote Link to post Share on other sites
gogmorgo Posted March 25, 2016 Share Posted March 25, 2016 Upgrade the harness and see what happens. Led's, especially cheap ones, can be sensitive to low voltages. Something else that may be worth trying is reversing polarity to the high beams. Quote Link to post Share on other sites
ComancheKid45 Posted March 25, 2016 Author Share Posted March 25, 2016 How would you go about reversing the polarity?..... Electrical work is by far my weak point. Quote Link to post Share on other sites
gogmorgo Posted March 25, 2016 Share Posted March 25, 2016 Thinking about it some more it wouldn't be easy. Because the ground is shared with the low beam internally to the "bulb". Obviously was not at my brightest when I wrote that. Pun totally intended. Upgrading the harness may work. Try running jumpers straight from the battery to see if the bulbs even come on. Are you sure they have a low/high setting? Quote Link to post Share on other sites
64 Cheyenne Posted March 25, 2016 Share Posted March 25, 2016 Where did you get the lights, and the brand (so I don't buy the same ones) got a link? Quote Link to post Share on other sites
ComancheKid45 Posted March 25, 2016 Author Share Posted March 25, 2016 Theyre these exact lights. https://youtu.be/TUYjrOvQrdc Purchased from an Ebay dealer http://www.ebay.com/itm/151777043125 Quote Link to post Share on other sites
MJam86 Posted March 25, 2016 Share Posted March 25, 2016 Kinda sounds like a bad ground to be honest. Check your ground and fuse just in case. I upgraded to harness and have no issues but mine are completely different Quote Link to post Share on other sites
ComancheKid45 Posted March 25, 2016 Author Share Posted March 25, 2016 I ordered a harness upgrade kit. I'll toss that in and see if anything changes. I read that through the 25+year old factory setup only 10.5 volts only show up to the lights themselves. We'll give that a shot and go from there. Quote Link to post Share on other sites
64 Cheyenne Posted March 26, 2016 Share Posted March 26, 2016 Did you test them straight to the battery, to verify that they are working properly? And those are the ones I was going to buy.... Quote Link to post Share on other sites
Megadan Posted March 26, 2016 Share Posted March 26, 2016 Did you test them straight to the battery, to verify that they are working properly? And those are the ones I was going to buy.... This^^ as mentioned before by a couple people, jump em straight off the battery and see how they light up. Quote Link to post Share on other sites
