I too like the nightbreakers. big improvement from the old ones.

LED for a H4 lamp is a bad solution as the geometry of the light will rarely be correct. Not sure if it is at all possible.

But the 150% and even more, wouldn't those burn the reflectors?
I would be careful to recommend them, just swapped the headlamps on my VW T5 because previous owner had used wrong bulbs. it was a pain of a job btw...

Thanks guys for all your comments.
Before I saw all the replies I rightly or wrongly ordered some Neolux H4 +50%
Thought it was worth risking from carpartsforless (£10).
Will let you know how it turns out when I get round to fitting them.

Cheers, John.

The 190%bulbs I have are the same idea as the Nightbreaker, the filament winding is the same resistance as a normal 55/60w unit but the mixture of gases in the bulb is different. Instead of halogen they use things like xeon in a proprietary blend that gives a whiter light.

What burns lamps and wires is using higher wattage bulbs like a 100/150w. They are still halogen but have a much higher resistance filament winding and run an order of magnitude hotter than the normal bulb so can easily melt plastic reflectors and draw too much current for the standard wiring

Yes I know. Double the watt and you have double the temp. Loss/heat is almost constant for same kind of bulb. But I thought different gases could give higher temperature as well. .

Not entirely sure if the different gases are hotter or not but but I haven't experienced any detriment in using them over a significant period of time in various vehicles.

I think if you have a higher wattage then the resistance is lower, „closer“ to a short circuit.
