Check it out in what sense, Bernie? Not working at all? Or misbehaving? In which case what are the symptoms?:nusenuse: Is there anything else electrical not working?
Have you checked the relevant fuse?

First check would be the bulbs if it's got them. If it's led then not so easy. Either way you need to check you have 12v and a good earth to the bulb/cluster

I wonder then if it's a 12v signal or a pwm/duty cycle signal for brake / tail light. Never messed with the newer design on a bike before.

I think PWM might be very common (hence many modern vehicle lights appearing to flash on camera footage?). I hadn’t ever thought about this, but could the use of PWM indicate that one set of LEDs would be operating dimmed as tail lights and full brightness (or greater brightness) when brakes are applied. Which begs the question of why only the tail light function is absent? Dunno...:nusenuse:

I've seen single filament bulbs used on cars that function as brake and tail.

Yes I agree with you. The only answer I can think of is its not pwm and its in fact 2 sets of less with 2 control wires.

Back to the nitty gritty of the question, having taken the seat off, is there anything identifiable as removable bulb holders or access covers in the rear light housing, Bernie?

Sad to say that, on the face of it, it does seem that this is a ‘sealed’ unit with no user serviceable parts though.

The tail lights are LED so its a trip to the dealers I'm afraid.

The brake and tail light uses several LEDs. If there is a LED which is not turned on, see your dealer for this service. PP94 of owners manual

Well that’s progress then ......grrrrrr. What was wrong with a £1.50 bulb every so often....?

As for house lights (Ahem, lamps sorry....), the life expectancy of LED / energy efficient ones has to be the most exaggerated claim heard in years. They go nearly as often, and take down the trip every time....! AA :beer-toast1:

LED bulbs tripping out the consumer unit circuit? I’ve not heard of that before. Halogens yes.:nusenuse: And the only LED domestic bulb I’ve had blow to date is one of those fancy decorative ones that mimic old fashioned filament jobs. I’ve even dropped LED work lamps from about waist height and knocked them off the workbench - they just kept on working.

But incorporating non user maintainable light units on a bike? I think Honda have lunatics running the asylum.:(
