LAMPF warning came up on dash. Changed both bulbs. High beam bulb blown. Still have dash warning and the head lamp is working when I switch on the high beam but is off the rest of the time. Use to he always on. Any ideas? Thanks.
had the same Lamf on my 1200GS a couple of months ago. Booked it in at the dealers, and guess what? The morning I started off there it the fault was not showing.................
Set off anyway to see if it reoccured but once at the dealers they told me that if they wired the bike up to the diagnostic thingy it would give them a 'Fault History'.
True to their word it indicated that the fault was an intermitant loose conection of the rear light. Not enough to make the light fail, but enough to show a voltage drop.
They replaced the rear light unit complete and the fault did not reoccur.
