Hella H4s will fit directly into an HG.
A relay will improve the lighting slightly, but you don't really need a it, the H4s draw less current than sealed beams.

Yes, but you need to allow for the park lights if it's a 73/74 model. Dr Terry. _________________________________________ When calculating a car restoration budget, be as accurate as you can & then double the final figure. It will be closer to the truth. |

Sounds like you need a relay to me. Too much current through the switch.

It all boils down to current draw. An original 7-inch sealed beam headlight unit is rated at 70/50, which means 70-watts on high beam & 50-watts on low beam. A normal H4 dual filament headlight globe is rated at 60/55 (60W hi & 55W lo), so the total power when on high beam in a H4 is 2 x 60-watts (120-watts) which is 10-amp current draw. Normal sealed beams are 2 x 70 = 150-watts or 12.5 amps current draw. If you start fitting 100 or 130 watt halogen globes, say 4 of them, this totals a possible maximum of 520-watts, which is over 43 amps. A headlight switch, which in the case on early Holdens incorporates a thermal circuit breaker which would burn out big time under that sort of load. This is where relays are required.

Can anyone help with this one. My Hq with standard sealed beams is fine on normal beam but the lights will start to flicker and cut out if left on high beam for more than about 10 minutes. I get around it by not keeping high beam on for too long.
Thats fine, but if someone can tell me what the fix is that would be better.
Thanks for any advice
