I think the 106 takes your common-or-garden H4.
I may or may not have done bits of illegal wiring in the past. Sierra's have MUCH better main beam performance when you fit 120W bulbs to the inners and then rig the relay so that both filaments of the accompanying 120/100 H4 light up together![]()
Did the bulb not overheat at all? Also did you change the guage of the wires? I guess I'd just relay it up in the same way as I did with the Dolly?
Very similar. Initially I used standard wiring and no relay - it burnt out the indicator stalk. So I chopped out the standard loom for the lamps, keeping only the "feed" for main beam and dip. Hooked up one relay to the dip feed and a second relay to main beam feed, took a power feed to each relay straight from the battery, and an earth for each. Used nice chunky wire (I don't remember the specifics as it was a few years ago)
With both filaments on yes the bulb gets very hot I'd imagine, I owned the car 6 months and didn't blow a bulb and used to use it a lot at night.
The Manta now has a similar setup![]()
I guess thats the philips 120W bulbs? Would be very good that setup.
An H4 bulb is twin filament, one for dip and one for main beam. 2 bulbs in one![]()
I guess thats the philips 120W bulbs? Would be very good that setup.
Edit - Damn it's a lot harder on the MX5, the battery is in the boot!
How does the live come through to the engine bay? Many cars will have a "live post" or a distribution block where it comes through, that's how I did the 205.
