Weird problem with number plate light - Help Please

I fitted a new led number plate light n connected those wires to those of the bike oem wires. when turn the ignition on, the number plate light stays on n normal . But once I fire the engine . ...the number plate light will start flickering n will never stay constant. I took it apart today to check the connections n all seem good . I'm baffled . Do you think it might need a resistor of some sort as go between .

Any help is greatly appreciated . Thanking you all kindly

 

I have no idea . it's a 2011 plate (new shape ). I'm just confused as mentioned all good up until the time you fire the engine

 

Oh boy.....

Thanks a million to all for getting back to me .

I'm going to see if I can find a decent led one. currently I've disconnected the lights

 

I need to look into this. I will Google it n see where I can find one. Cheers buddy

 

A while back I installed healtech brake light modulator. I had to ground one of the wires to the frame. I'm thinking maybe that the current is going to the earth before it reaches the led light . So maybe I could try and remove that wire n run it straight to the battery negative terminal .

Or am I talking crap

 

Ok...I have now removed the ground fire from the rea r frame and taken it direct to Negative battery terminal. It's still bloody flickering :-(. I think it's the main connection point from led wires to OEM. The led wires are flimsy. I will try soldering them to see if it helps. Failing that I have bought a decent UK made one which I am going to try it on. And if still the problem persists then remove the brake like modulator and put everything back to normal and see how it goes. I don't mind the tinkering in Summer but in winter :-(...It's awfully cold. Anyway what choice do I have....I need to get this solved.

 

You know after I try the methods I mentioned n if I still have issues......I'm getting rid of that module . It cost 40 quid +Plus stress + Time.

 

Oh lord...I sincerely hope I have not offended any nations here. If I have then 1st thing in order...please accept my apologies.

I am clueless and petrified when it comes to electrics. I am running without number plate lights now :-(. I will start doing some research into what you said about rectifier.

I had look at the above topic and I am completely lost. It feels like a bloody PhD course to me :-(.

 

I just pulled out the original ones last night. That's the next task. I will give that a go tomorrow or Friday .
