Mood: Awaiting the arrival of the sun and the disappearance of the rain
I guess when you say 'Hazard' you mean both sides (L&R) flash at the same time????
Check all bulbs for any loose or blown connections. Only time both sides flash on mine is when the alarm or immobiliser is armed. Have you one of these on it and is there a problem there????
Have you been out in the rain at all?? Take top half off of the indicator switch on the LHS bar and clean/lube all contacts/moving parts.
Not had it myself on my '01 748R but it sounds like a simple lecky fault. Just need to find the source of it.
