You're lucky to have a warning light!
Mine popped the switch our of the thread in the casing (not uncommon, apparently). It's been replaced by a superb bodge with a bolt and nyloc nut
It's due an oil change, though, and it's always nice to see that red light extinguish after you've filled her up and fired her up.
I'll have to get around to getting the casing helicoiled.
