Whilst checking the correct wire to tap for high beam control of my spotties I noticed that the voltage on the high beam line at the headlight was a mere 9.8v whilst the battery voltage was 12.1v. That's a voltage drop of 2.3v on the high beam feed line. No wonder the headlights are so dull.
Without compromising the Army appearance of the vehicle, what do you suggest to improve the brightness of the stock headlights?
