be careful mate you will possiable melt your headlight plastic andruin the chrome stuff and you could blow your electrics keep with legal bulbs you dont want to get pulled for illgal bulbs do you. if you really want bright stuff get a HID kit expensize but very bright and legal

[nov4]

there classed as legal on mine as its an '85. but standard ones are crap!!!

can anyone else help me?

cheers

100 watt bulbs are legal as long as you get legal ones.

To run them through a relay you need to run a live straight from your battery through the relay and to your lights then from the lights down to earth.

Then to turn the relay on and off you need to run a wire from your light switch to your relay and from the other side of the relay down to earth.

When you buy your relay it will have a diagram telling you which pin does what. If you dont get it just ask me.


power divided by volts will givbe you the amps it will draw.

100/12 = 8.3333

so in the line from your battery to the relay put a 10 amp fuse in as close as you can to the battery.

this process is the same as wiring spot lights by the way!

Landy Lights are on a level with Nova ones, I was just going to get spots along the top of the windscreen.

loads more than standard.... cause i had 2 novas... on with 55/55 and one with the 130/150 and the difference was massive

[Nova-Boy]

you can connect either side of the bulb to the relay and the other side to earth. Split the live from the relay to go to each bulb and then from each bulb down to earth. This makes them in parallel rather that series.
