Hi guys. So I sourced some eBay specials to try out, two sets, one appears identical to the originalcaferacer ones and the others with the halo which again look identical to ones from kitcardirect. Just comparing DRL options below, haven't looked at beams etc as would probably take them somewhere to get the alignment correct.
Original side lights
Original cafe racer style horizontal bar
White Halo
Amber halo, can also be used as indicator as mentioned by others.
I really wanted a yellow DRL rather than white or amber so will keep searching but any of these make you more visible. I think I prefer the horizontal bar but wife and kids like the "surprised" look of the white Halo rather than the "sleepy" look of the horizontal bar.
I've fitted spade connectors to them all so can swap around easily when the mood takes me.
Thanks @PlastererPete for the tips!
