driving lights wiring help needed please

I just received these driving lights and was excited to see how bright they are.

When I put power to them I got a surprise. they have multi function to them. The first time I touched the power to them they pulsed, the second time they flashed and 3 flash sequence and the third time I touched them they were constant on. They came with no instructions. I plan on wiring these on a switch, powered by an inginition switched power source. I know how to do that, my question is, is there a way to stop these lights from changing functions each time they are turned on? How do I wire them so that they are either always constant or pulse? I will except either. Anybody out there have experience with lights like these?

I'm hoping you electrical guys out there will chime in and come up with something.

The only legal mode, in the USA, is constant-on; flashing would be illegal in all 50 States... Headlight Modulators do not "flash", they modulate the lights. They are only legal to use on the main headlight, as well.

As for the different modes switching, that is controlled by a circuit inside the assembly. No idea how to hardwire it into a particular mode, without opening one up, to see if the switching circuit could be bypassed (if they use a current driver circuit, you may not be able to bypass it by soldering a single wire...). It may be possible, it may even be quite easy, but I'd have to see its guts before I could suggest how to do it.

These LED's might be illegal due to them pumping out what appears to be 1,200 Lumens each. A normal, legal headlamp, is rated at around 700 Lumens for the Low Beam, and maybe 800 Lumens, typically, on the High Beam (55 W/60 W standard bulb). HID's, however, claim to pump out 3,100 Lumens, so it's hard to say if these LED's will get you pulled over, or not. Might want to check with your local LEO"s. Cheers!

After I posted. I realized that the pulse would not work because of the laws plus they need to be constant at night. Constant in my only option. I've opened one up and found no switches or jumpers. Didn't see anything that looks like it may be adjusted. I'm guessing there has to some sort of calibration sequence to setting a particular mode.

Hi, A few months ago I fitted a set of driving lights to my friends BMW 1100. They came from China and did the same as yours. After a lot of looking on the internet I found a site where someone had sorted out this problem, You have to short out two pins of one of the two IC’s. That did the trick. Worked a dream after that. Here is a “You Tube” link of what to do:-
“How to remove strobe and low beam mode from U5 U3 motorcycle LED fog light”

I hope this is of some help.

Worked like a dream. super easy if you have any soldering experience at all. The only issue I had was that each light had different circuits in them. the first one I did matched the video exactly. The second light was different but with a little patients and lots of probing around, I did find the two leads that needed to be crossed. Only this time instead of just a dot of solder joining two adjacent leads, I had to create a jumper to jump across the part to a lead on the other side. In the end, they are both constant on and ready to be installed onto the crash bars.



Above you can see the two different circuits that I found inside the same lights. They show the two different jumpers I had to perform. The one with the wire needs to be from the top left most in the photo to the second from the right on the bottom. The other photo shows that you just solder the two lower center terminals. Hope this helps anyone else who may need to fix these.

thanks again to the great people on this forum.
