When doing an electrics test recently the beacon refused to rotate, only lighting up. We decided to remove it and see inside, as we don't really need it most of the time anyway.
Something got very hot here.
Looks a bit like a resistor between the live feed and the motor, but difficult to tell. The beacon is Bosch made, and not a type JCB offered (as far as I know). I don't know if anyone knows where to look for spares, but it looks like they'll be difficult to find at best.
Anything you find is very appreciated.

Probably an RFI suppressor to tame the electrical noise from the motor.
If you want to maintain 'the look', the easiest thing to do would be to gut the lamp you have and mount a modern LED or strobe inside

Re: Mr. MacGregor beacon
I tried changing the bulbs in our rotators for leds. Originally they were H1 halogen so swapped for an equivalent led. Obviously the light wasn't designed for led as the bulb drain controlled the speed. The result was the rotor spinning at probably double speed and the light lens itself showing almost white.
If a LandRover doesn't leak oil, it's run out.

Re: Mr. MacGregor beacon
Not quite what I had in mind. The burned cable suggests the motor is seized and probably isn't a viable repair.
Mounting a modern strobe under the existing lens will keep "the look", but save a lot of work and give a better result.
A xenon strobe will put out more light than the original ever did.

Re: Mr. MacGregor beacon
Thanks for the ideas, I should have said that connecting the motor directly to the battery makes it turn, but it doesn't seem to enjoy it much. I do still think it's a resistor, but it does seem strange to have one if the motor is supposedly 12V. I think I'll need to get the motor off and see what I can see on it, it might not be 12V after all! I'm hopefull it'll just be a question of getting a suitable replacement part for the resistor or suppressor. I couldn't see the link Ian, but as there's no urgency to fix this I'm not bothered about putting lots of work into it, I'm more than happy with the H1 brightness and not keen to overload the electrics by fitting very bright things anyway.

I'm not familiar with Xenon bulbs (we might look in to it some time, but I don't know when), but for now we'll use the spare H1's we have, before we decide on anything else.
