HELP: light warning light on W639

7482 Views 4 Replies 4 Participants Last post by  alloutallup

My light warning light has come on in my new style vito (bottom left corner, little light blb with lines coming out of it).

my offside light bulb was dim, but still was goes to full beam. I changed the light bulb and it has not cured the problem. also noticed my rear left hand side license bulb is out as well

this makes me think it is a fuse? if so which one, as i had a look at the manual and could not see which fuse is for this.

Any help greatly received. need to get this fixed as it is dark up here in scotland!

all help is greatly appreciated.

If one of your bulbs dont work fully the light will come on, once you replace the bulb it will go off then. I bought a new head-light bulb and replaced the faulty one and the light went off. Simple as that really. Hope that helps
