Back in the day I upgraded my 86 Audi coupe quattro to 100Ws all round, H4s and H7s so that was 400W main beam - before LEDs came about - but they have metal buckets and glass lenses with high watts you could melt the plastics - oh and a wiring upgrade to carry the extra current.
The road was clear at night lol must remember to remove them when i get round to putting it back on the road....
