hair trigger for hi-beams 300D
 

The lever that controls the wipers\turn signal and hi beams on my 1985 300D is exceptionally sensitive when it comes to turning on the hi-beams, which is probably quit a nuisance for other drivers on the road as they flash whenever I access anything on the lever, to turn, clean the windshield, or just tap it with my fingers while driving. Any recommendations on how to allieviate the poblem? Thanks
