Does anyone have any actual experiance with these bulbs rather than hear say?

Can anyone tell me what wattage the standard wire is able to cope with or how to test it?

I can easily make up a relayed loom but I would like to get away with doing that.

been running with these for about 2 years now and no problems.
But i do think JDM and UK cars use different wires though so it may be worth stating what car its for

JDM's and UK's use different gauge wire, surely not!

keep a eye on the connectors on the lamp itself, if they are loose that will generate heat.

I would get some Osram Nightbreakers (+90%) or similar - I fitted them to my car and the difference was well worth it. I had some Philips Xtreme bulbs in my previous car and the difference was similarly impressive. I would be worried about the heat generated by the 100w bulbs and their effect on the headlamp loom with the extra juice going through it.

Dan: drop harvey a PM, he is currently using Philips Rally 100/90 in H4, and will tell you what you need to know.

If it were me, I'd make up a fused, relayed loom. www.vehiclewiringproducts.co.uk.

You still have the extra heat on the plastic lens.

I use 100 watt bulbs in my driving lamps,no issues with the lens or the wiring loom,along with the phiips extreme vision headlamp bulbs in my uk turbo.As said above osram nightbreakers are much brighter than your o/e bulbs and only cost £12.00

I've heard reports of wiring overheating and CERTAINLY poor connectors doing so and even melting, but I've not heard any reports of lens, or reflector damage.......yet.

I know I could make a loom, I have done it many times before on my other cars/vans for spot lights and the like.

My question was more along the lines of; Do we know exactly what the OE wiring (assuming it's in good condition of course) can take, or to put it another way, the maximum amps the OE wiring can run at safely?

Has anyone actually tested it?

Have a alook here: http://www.vehicle-wiring-products.e...e/thinwall.php

The stuff used on Scoobs is the Thinwall stuff mentioned here and each thickness is given a max current rating.

I THINK the headlight wiring is Ref16, therefore 32/0.20, or thirty-two strands of copper each one 0.2 mm thick. It's rated as 16.5A, so would be enough for a 100W bulb.

IF, however, it's only the Ref11, it's only rated at 11Amps. Which should, in theory, STILL be enough for one 100W bulb.

DO ensure any connectors are TIGHT though. A loose one puts resistance in circuit and resistance = heat

jdm dipped headlight wiring is heavier, on my my05 jdm the gauge of wire to feed the hids is defo thicker than the wiring on my old my03 uk wrx.

Had 100 watt bulbs in my car, no problems with the reflector, just the longevity of the bulbs and connectors was NOT good.bulbs do not last as long as lower wattage ones, the connectors become brittle. (even after making sure the terminals in the connector were snug)

NOT recommended
