Bobber headlight indicator question (flashing led)

[Harry44]

I have bought a cheap LED 7" light from ebay for a bobber project i am doing

There is a 'halo' ring on the outside of the light which when you apply 12v it lights both sides up orange, i want these to be powered individually to have more vision of indicators to oncoming traffic rather than just the bar end indicators.

So i have heated up the cover, got inside the light and cut the cables from the board and soldered them to i can just apply 12v straight to them.

When i apply 12v to each side, the left comes on perfectly and constant, but the right hand side has a steady flicker.

My question is, is there something in the board that would stop the led from doing this, have i got a faulty LED unit, do i need to add something in to stop it.

Just a bit baffled as the left hand side led works perfectly?

A link to the light i am using to give you an idea-

Wild guess but is there something that lets 2 units flash that's still operating on the one side ? I've seen the "angel eyes" being used as indicators but no idea if that's on board or a separate unit

can you post photos of the inside of you light, the circuit board, the leds, and anything.everyhting else?

for a flicker I'd say it's a dodgy PWM driver or you're not powering it right... but it's weird that it works at all tbh :-o

One side may just be coincidence or luck more tolerant of the 12v feed. I would expect them to need either PWM as above or some form of current limiting?

Here is the light in question, i understand now that i shouldnt of just applied 12v straight to it, so what am i going to have to put between the feed and this? That is small enough to fit inside the headlight neatly?

Looks like 2 different sets of leds on that strip,
Are they the kind that light up white for drl and then the white ones dim/turn off when the indicator is on?

If so then you might need different voltages to drive the 2 sets of leds if there is only one pair of wires there. Or it might be the polarity needs reversing to change between the white/yellow.

It's odd that one light is working and the other is not though, as supplied I would have thought they would be ok to have 12v directly fed to them (providing they are not 6v motorbike versions!)

Yes one DRL and the other feed is for indicator, definitely 12v

Put up a photo of how they were originally connected, if the feed to them was via a board you might have to replace that with an external/extra board.
They are available cheap enough if required

it looks like there's only 2 wires in the photo?
