I have fitted front and rear lights that run off my 36V battery. The front is plenty bright and has a horn too.

The rear light is a bit of a mess\kludge however and fitted on the seat stem.

What I would really like to do is fit a rear LED light on the rear mudguard.

Can anyone suggest suitable 36V rear LED light for the mudguard ?

Although any voltage might do, a step down converter would be easy enough to arrange.

There are lights, some with a built in remote control alarm system, for very little money that fit "under" the saddle, actually attached to the saddle metalwork, and are therefore far better protected against water for example. Mine is several years old and can run several weeks between charges.
It can be also used as a warning device, but in my opinion, is simply not quite loud enough in that role, but as an alarm, is around 100db.
If you fit a rear light to the rear mudguard, may I suggest one with a GPS tracker built in (or you build it in yourself!), just in case your bike gets stolen. The tracking software (ones I have seen and/or used) is easy to use and can be had as an app on a smart phone for a single payment of under 10 UK pounds.
It can also be controlled/checked, using simple text messages if needed.

That a possibilty I had not thought of, a rear mudguard light would be a good place for a stealth tracker, any examples you know of ?

I could build one myself, I have built quite a few very long distance point to point GPS trackers based on LoRa, see here;

But it could be a lot of effort to design and build a very compact and robust mobile phone type tracker that looks like a rear light, sometimes just spending money is the better option ..............................

Look on ebay, there is quite a selection, though some are not "true" GPS Trackers, only "Mobile Phone" trackers, that are not as exact, especially outside of cities.
Make sure that you ask the seller in an ebay email, EXACTLY, if it is a TRUE GPS TRACKER, then you can get your money back from ebay very easily! It happened to me twice.....
True GPS bike trackers are generally quite small nowadays (and probably will continue to get smaller!), so measure up carefully and you should be able to manage it. My first GPS Tracker was quite bulky, so I made up an attachment for under the saddle, above the rear light fixture, with a hidden wire for charging.....It worked, but it was not "pretty!
I am surprised that relatively few people have them on their bikes. In test some years ago, using our car, I could tell which lane the car was in on a multi lane Motorway!!! Pretty exact!! Better than claimed.
I hope this helps.

Might need a bracket fabricating, mine is fitted on the carrier, with microswitches on the brakes to work the brake light.
