Hi culzean
Looks lovely
Please could I ask if your link to bulbs are the precise bulb I would need for a 2013 jazz si
Many thanks
John
Yes you need the H4 type at £70 a pair

As you can see the LED throws a lot of light on both the nearside and offside verges, the light quality, spread and beam cut-off all better than filament - they also perform well in the wet (where the old xenon bulb light used to disappear).
Just be aware that these bulbs will not melt the ice off your headlights in winter because they don't produce very much heat at the front end (just a lot of white light LOL), the heat comes out the back of the bulb via the black finned heatsink, which I have found runs at about 60 deg C (just a bit uncomfortable to touch).
Just make sure the rotation position of the bulb body to location pegs is in position 8 (as per instructions with bulb as the position for RHD) - mine were delivered like this but I just checked and tightened the allen locking screw (a pair of allen keys are supplied - one for rotation lock and one for heatsink).
The only extra thing I did was pop to Maplin and get a syringe of non-setting thermal grease / paste to smear on the heat-sink threads and as well as aiding heat transfer I am confident it will stop any corrosion between bulb thread and heat-sink thread. You only need a very small amount but if it gets on your fingers it goes a long, long way and quite difficult to remove - after the first encounter I used thin vinyl gloves for the rest - I did also put a bit of silicone grease on the threads of the 4 pin screw plug as well, as I found that these can quite difficult to unscrew later ( after initial trial of bulb I unscrewed heat-sink to put original Honda rubber sealing collar back on light bulbs) - especially if they have heat-sink grease on the thread LOL (the 4 pin connector has to be fed through centre of heatsink and it is a neat fit, so impossible not to get paste on it), but because the female threaded collar is flexible you can kind of 'push' them off the thread with your thumbnail without damaging them.
