My Sport should have had the rectangular light but that came as a spare, the bike being fitted with the concave Cibie unit. The only longish night riding I have done was in very dark France and it performed well. At present it is running a Phillips Vision Plus bulb which is probably past it’s optimum now.

I have looked at Paul Geoff's site but the bulbs are a bit expensive to buy if it turns out that the wiring or the reflector can't handle it. I don't mind a £15 bulb that doesn't work but a £40 bulb is too much to sit in a box

Be aware of my experience with the rear ones.
As they shine directly at the back of the reflector, I found that due to the nature of LEDs, I was getting little or no light off to the sides and precious little from the back. It was actually dimmer than an old-style bulb. This was a few years ago and the designs may have changed so as they say, YMMV.

Cheers,

Something like it's better to use white LEDs with a traditional red lens? Or vice versa..I haven't worried about the rear lamp since then, it's only 5 watts and if that is critical you have problems elsewhere to fix!

One thing with the LED headlights is that they can flicker, this is caused by a feedback loop through the Main Beam warning light, this can be fixed by putting at least one and preferably two diodes in series with the warning light bulb, or leave it out entirely.
