I did the mod last night to have the high and lows on at the same time (splicing the violet/white and light green wires under the steering colum together), but now have a problem.
It works fine on the drivers side headlight but the passenger side still works normally.
Any ideas?

 

When i did mine it worked both,I dont see any reason yours wouldnt unless the bulb is burnt out but i imagine you checked that.

 

Try the sports model head lights!! that will do the trick!
