Thanks Simon for the thought. Sorry you have the same problem. Pretty ridiculous not to be able to get the highlights working! I have tried everything (including your suggestion,seeing if there\s current coming to the bulb, the fuses, etc.). Nothing. Not sure what to do, for now surviving with the low lights. Best, Iain
there is a fair chance that your multi-function switch (controls high beams, turn signals, etc.) is to blame. I would see if you can swap an used one from a junk yard car to see if it makes a difference.
