Who you is? Where you stay? Whatchu do? How'd you find us? Have you tried checking your oil level? Sounds like you might be a little low.
What my biker brother "Badbrad" is trying to say is that we have identified your 1st post to be a question..
Typically your 1st post should be an intro ....tell us a little about yourself..
Dim oil light ??? that happens on my scoot when I get my instruments wet from washing ... goes away after iit dries
oil sending unit is an on / off type of signal ... it will either be on (bright) or off.
check and dry your connections to your instrument.
