The BEST and (sadly) very EXPENSIVE option is to fit a pair of JW-Speaker adaptive technology lights. They are really outstanding in curves.
I have a pair of the very first edition fitted. Steve (aka
@1olbull ) has upgraded now to the GEN2.
Once you have ridden adaptive - it will spoil the choice of using ANYTHING ELSE at night. Really.
I have read there are some Chinese copies of the adaptive, but have yet to see any info.
If you do not ride much at night or hardly ever hit curves - then there are loads of options.
The Triumph chrome shell bits are fine really. Basic chrome 5&3/4" cups laid over at 90°
I did look for a replacement but I don't have the sort of Harley Chrome Bits access you guys have.
It's the headlight innards that are SH1T POOR. The Reflectors are plastic - poorly designed and poorly mirrored.
The mirroring will eventually burn off and the plastic goes fragile.
The JWS will drop straight in - though you will need to cobble up some wiring to connect the position light.
