H4 wiring harness upgrade

[vinnY]

harness looks the goods
specs look alright, just as long as it's bigger than 12ga it's probably a decent kit
bit skeptical about the lengths but they can be extended of need be(if you want to tuck the wires to hide them a bit)

Damn it, they are only 14ga wires, is that gonna be a problem?

[vinnY]

New & Improved Wire Harness features:

2 OE/OEM Bosch/Tyco (AMP/Potter & Brumfield) 40 amp relays (single or dual 87 outputs)
Heavy Duty interlocking relay sockets with mounting tab
Fusible link (slow reacting fuse protection) & separate blade fuses for low & high beams
12 gauge automotive wiring for main power
Black split loom matches OEM to protect against heat and elements
Male connector(s) to plug into existing headlight socket
(2 or 4) new headlight sockets (depending on application)

thought it was 12ga? or you might just have to buy the super heavy duty ones

[NightKids]

Yeah I think it's only 14ga...

'The Heavy Duty models are 14 gauge and use 2 relays'

Seems like an alright kit and the price is pretty good ($65US inc postage) so if it's gonna save me heaps of trouble, this kit might be the GO!

isnt 12ga thicker? so why is the heavy duty use thinner wire?
65us seems pretty good. tempting.

heavy duty = 14ga
super heavy duty = 12ga

Just so you know, so you don't have to run all over the place getting bits and pieces, Ashdown-Ingram stocks all the auto electrical parts you'll need. There's 8 branches in Vic listed here.

Use a resistor relay instead of the diode relay too. Less chance of it blowing

wouldn't it be cheaper to get HIDs? less fuss also.

I had 100w bulbs in my car before i got HIDs and they were fine.
I did though see some people have burnt plugs & the headlight housing burns.

That's why i opted for HIDs. 35w HIDs are as bright as 100w normal bulbs.
If you want super bright 55w HIDs are available.

Everything though is supose to be for offroad use only, when it becomes higher than normal lighting

^^ Yea it would be. Using higher wattage bulbs is what was used in offroading before HID's became incredibly cheap. Just wait till LED's take off in the next year

[Limbo]

lumex type bulbs are even better! less power and brighter yet!

i've got them in my torches and they blitz the LED ones

[02gzm]

Lumex is a company :P They use the same superbright LED technology that other companies are starting to use. But yes, they did pick up the ball quite early on the bigger LED's.

I was talking about automotive LED's. They can put out more than double the light output of HID's. Just too expensive for your average car these days though. But in a year you'll see them as OEM equipment in basically everything. Some of the large prestige car manufacturers use them already. Take Audi R8's as an example. The entire headlight uses LED's.


HID's have reached their peak. They cannot evolve into anything better. LED's are the lighting of the future.

Yeah I've seen my friends HID lights in halogen housing and the light just scatters everywhere and blind people! Plus I didn't wanna attract any attention with the cops and quite enjoying the challenge of getting a tough halogen setup...

Although I have seen a HID kit where the top of the bulb has a metal cover that minimizes glare..
