Led front headlight goes off when revved

[savage sausage]

Ive wired up a new led bulb directly to the reg/rec it powers on when idling with a slight flicker, but when the engine is put under load it goes out.

What have i wired up wrong

Try put a large capacitor as a faux battery, say 1000uf or ideally more and 25v rated. Or hook up to a battery to check. Regulation can go screwy if it sees an open.

Thanks for the reply
In short the 2 wires from external genetator are wired directly into a new Reg/Rec , and the headlight wired up directly to R/R (no switches wired in yet)

so where do i put the capacitor?

Is a bigger uf capacitor better ? 2000/ 4000/ 10,000

2200uf 25v will be fine, and what I've used in similar setups.. A 16v will be too close to the line but would be OK for a test. They will be polarised so + to + power.
