Never ends eh? Car is 33 years old, headlight switch has lasted that long, what am I doing?
When researching headlight bucket rust repair I came across the recommendation to install the h4 update bulbs. Along with that recommendation came suggestions to install a "headlight switch bypass relay". In the stock configuration the electricity that goes to the headlights is channelled through the headlight switch on the dash, and also through the left steering wheel stalk (for highbeams).
