Headlight bulbs

[chukkacarne]

Hi
I can't find the answer to this so here goes!
I got a lhd 69 tintop with original style bulbs think there 410 style?
Can I fit h4 bulbs directly into lights? Or do I need to buy new units?
Can my wiring, switch and relay handle the extra power?

I'm sure someone can help.

Thanks.
James

You possibly need a conversion bulb, like the one JK offer (part No J10654).

But I am not an expert on US-spec buses.

You will need the little plastic converters to use h4. I put um in mine a few years go cound not believe the difference lol actually being able to see where I was going.

Thank you all for help.

I opted for a conversion bulb and works great I can now see at night
