How to keep main lights on when using high beam

[slay 25]

Hi,

Please excuse me for asking a question that must have already been asked before, still a newbie here!

I understand the UK S4s would switch off the main dipped beams when high beam is switched on.

Has anyone modified this so that all 4 lights stay on when using high beam?  There are 2 positive wires and one ground for the low beam.  Do you just need to run a diode from high beam to one of these wires?

Thank you in advance for the advice.

Thanks for the link.  Would this actually light up all 4 lights when using low beam ?  I will have the H1 socket on my so obviously would not want to have all 4 lights on when using low beam.  Thanks for the advice!

Not sure what you want to achieve. With a 5-pin relay like @Bibs posted on high beam you'll have 4 lamps lit: both interior H1 bulbs and the high beam filament in both outer H4 bulbs.

Or do you want to keep the low beam filaments in the outer H4 bulbs lit while high beam is used (as is the case when you flash the high beams)? This would offer no real benefit but could cause the H4s to run hot as they're not designed for prolonged use of both filaments together.
