Would this work to prevent lb/Hsbc hyperflashing?

PS - pretty much everything after the first question mark is bs and can be deleted.

As for this:

You only need it if running LED turn indicators without ballast resistors, so yes. It should work.

 

Also, the cost is stupid but the Diode Dynamics version is pretty nice as you can program the 1 tap for 1 to 10 blinks. 3 is good and enable WigWag for better visibility when hazards are one.

It's on AmaZoo too. $50 to $60

 

Appreciate the help, thanks! I trying to replace LB /HB but despite trying several Led sets, and despite all the sers came with ballast built in , still all of them were hyperflasing. Was wondering, if for like the blinkers, switching the relay for HB/LB could prevent hyflashing?Thank you for your assistance!
I tried many LED sets to replace LB/HB, and despite the fact that all of the sers came with built-in ballast, they were all hyperflasing.
I was wondering whether switching the relay for HB/LB could avoid hyflashing, similar to the diode dynamic relay for blinkers.

 

The DRL's "HB" run on PWM. The voltages get cut in half. So I can see why your are strobing there. You will probably need a LED decoder even though your aftermarket came with its own. iJDMtoy has a decoder for the ISX50. It's labeled as R4 decoder. Best bet is reach out to them and ask if that decoder will work for your headlights being used as DRL. I'm not sure if you have the DRLs disabled or not.

Another is if you put the original halogen bulbs in the highs, and just use the LED headlights on the lows. Do you still get strobing? If so I also assume the headlights are messing with the headlights module. Most new cars supply power like this using PWM.

 

Yes I tried 5 pairs of LED bulbs and even added another extra capicitor (on top of the built-in) but in vain. These lasffit

Seems to work out of the box -do you know of these?
