I recently fitted a set of polo GT clocks into my 1.3 93 MK2F CL to replace the standard clocks without the Rev counter,I removed my old speedo from my old clocks and fitted into the new clocks with my Rev counter to keep my current mileage,whilst doing this I fitted a new indicator stalk as the old one was broken but since then the little blue light doesn't come on that indicates the high beams are on although the actual outside high beam is functioning fine,has anyone else have encountered this problem either when replacing a stalk or Rev counter clocks? My MOT is in less than a month so I want to get it sorted incase it fails on it

I take it you have checked the bulb ? The feed for the light comes from the R/H main beam fuse (#6) Check you are getting 12v at the speedo connector pin25 (Blue/Black wire)
