Spend a few dollars and have a relay fitted. That way not only are you able to fit higher wattage H4's but the switch on the stalk ceases to carry all the current required to drive the lights.
Every time you flick the lights, it sparks at the switch. The bigger the current, the bigger the spark and each time it does that a little more of the contacts goes. Failure is inevitable.
With a relay, the stalk switch only carries enough current to pull in the contacts in the relay which NOW carry the heavier current for the lights. Mini lights were not well designed compared with whats available today.
I have H4's on each of the cars we have that use 7 diameter lights and they are great at spotting roos on our rural roads.
Thanks for the heads up Mike. You learn something everyday. Not too concerned about higher wattage as my driving lights already light up everything from here to buggery away. What kinda costs and work are involved with doing it myself? Would the black book have anything on relays?
