Hello everyone....

Im very frustrated, I have had sooo many issues with these pre wired flexible led strips...its crazy!

I have 3, 9.5 ich led strips on each side of headlight. (total of 72 leds to each light)

you would think its simple cause only 6 wires total to connect 3 strips...but a few burn out, no once not twice, but a bunch of times. oznium keeps sending me replacements, which is cool.....but its bot fun once headlights are sealed up and have to go in to replace again and again.

this is the when I was making the board where they sit

this is it now once holes were punched and leds laid through backside

the problem is once you get up close you can see that a few are out...


Funny thing is sometimes the ones that are out....come back on for a bit and then go back out...

What exactly do you have them wired to? Straight to the battery? Or some other "12"volt circuit?

If your tapping into your pre existing 'running light' wires/harness, it may be underpowering or overpowering the Strips.

they are wired into the the parking lights. so when I turn parking lights on they comeon.

also, Ive had probably 10 strips to play with and I was just testing them on a 9v battery and some had tw0 or three leds out in a row.

but its odd, I saved two of the bad ones and just yesterday one of the bad ones came all on with the 9v.

justin has gave good customer service, no doubt. but the last time he sent me 4 replacements 2 out of the 4 were bad!

Id suggest just making something yourself with Prewired LED's or making a board for the back of it. Then you dont have to hope that the strip works.

Sounds like cold solder joints on the LED strips.

Good macro pictures of the strips would be the easiest way for the rest of us to see if that was the issue.

A voltage regulator and a circuit board with multiple series of LED's with resistors would be your safest way to make those.

All I know is your car looks sick. Nice job.

Try hooking the strips up to a 12v source. Hook them direct to your battery for a minute and see if they all come on. I don't see why that would change anything, but its just another test.

The problem is that the flex strips have cheap Chinese soldering. It'll become disconnected and cause 3 LEDs to go out (b/c they are wired in series of 3). If you bend the strip the right way, it'll reconnect and the LEDs will come on.

well, then I was thinking...instead of running a strip that has 24 leds attached to it.....I should run....8 small ones that run in a set of 3. 3x8=24 same as one strip.

maybe this way they dont go out...hmmm icon_confused.gif

The LEDs themselves are OK, but the issue is with the soldering and flexible circuit board. A rigid board would be a lot more reliable. Honestly what I'd do for the headlights is solder LEDs to a custom shaped circuit board. If you're not comfortable doing it yourself, theres a handful of headlight customizer people that could do it for a couple hundred bucks.

Now listen, I'm pretty up on my car lighting and new models coming out but what the hell kind of car does that Headlight come on? It's got like 6 or 7 projectors in it. Would anyone liek to guess what kind of car this is or is it a custom job? Looks sick!!! icon_eek.gif icon_biggrin.gif

It is a Lexus LS460h and its LED based headlights, not HID.
