Dunno about the 160 watt bulbs, never heard of them before?
However back in the late 70's / early 80's I had installed 55 / 100 watt bulbs in my 5 3/4" H4 Cibie headlights and 100 watt bulbs in my 5 3/4" H1' Cibie's....these were marked for off road use only at that time too.....I used them for years on both my Ford Capri and on my BMW 320i as well......you can only imagine what 400watts of hi beam light looks like.....frick
in wild!
Never had any problems with melt downs......of course all 4 - 100watt bulbs weren't on for prolonged periods of time.....was great for the country back roads we used to race up to the cottage late Friday nights......on
ly had to run relays for both the low beam and high beam to make sure the headlight / hi beam switches were safe.
