Working at a major autoparts supplier I've been able try out several combinations of globes and reflectors.
After trying several combo's I've settled on Narva 72000 polycarbonate inserts with Phillips +130 H4 globes.
Best combination of halogen globe and reflector I've tried. One of the best features is the ability to do river crossing with the headlights left on, (try that with glass!), especially at night.
The pic below is crossing the Murray river at Tom Groggin.
The LED inserts I've tried all have the same issues, too much reflection from pale coloured objects on and near the road and in the wet not enough contrast with lane markings.
I actually know of a Rubicon owner working at a well known Jeep parts supplier who went from JW Speaker to the Narva inserts due to reflection issues.
