- However, H4 bulbs might cause a problem
- I believe that one of the new MOT failures being introduced is that low beam must stay on when high beam is selected
- other options for H4 bulbs include stuff like this
- This whole thread has been about H4 hi/lo......:-/
- I seriously doubt that and it won't/can't apply to vehicles where there Hi/Lo beams come on separately from factory like the FZS 1000.
- This kit 'could' pass an MOT, but only with a much larger baffle. I know because my very first HID kit was like this and stock baffle isn't anywhere near large enough to provide an effective low beam cut-off. And that's only half the problem, the Hi beam halogen bulb is so poorly placed (its 5mm off-axis) you get fuck all hi beam.
The
ONLY half way descent solution/conclusion I have arrived at for the telescopic type H4 Hi/Lo is as follows -
- Construct a better 'hood' that surrounds the bulb, in order to close the gap between the inner baffle and the hood itself and have a bigger slot in the side of the hood for closer to stock Hi beam.
- Construct a better quality moving assembly with better tolerances as the gap between the housing the moving part on the majority of HID bulbs is far to large which results in the bulb laying at an off-axis angle.
- The above assy. dosent travel far enough, every H4 Hi/Low HID bulb I have examined either sit reasonably well for low beam but don't go back far enough for Hi beam or visa versa.
I have looked into a non moving H4 Hi/Lo that incorporates two arc envelops inside the one bulb, but:
- When you switch to Hi beam the warm up time could take a few seconds which is unacceptable, but I haven't researched this yet.
- The baffle that sits right next to the bulb to cover the low beam arc on most bulbs dosent cover enough.
- You would need to install 4 ballasts instead of the usual 2.
- And some of theses dual arc bulbs aren't directly in-line, on of the arc envelopes is little off-axis (see this image http://img.alibaba.com/wsphoto/v0/321736697/The-best-quality-H4-4-hid-lamp-HID-Dual-Beam-Bulb.jpg)
The only other options I know of are to either get
a pair from driving lights or
Hi/Lo projector to enhance existing low beam of the main headlight, or go the extreme route and retro fit
a pair of projector Hi/Lo units inside the FZS headlight unit. Someone mentioned about fitting 'Angel eyes' this can be done, but also requires the opening of the FZS headlight unit depending on wither you fit just an angel eye kit or projectors unit with built in Angel Eyes. And lastly LED driving lights, as this has only recently become affordable and the simplest solution as I dont believe they are effected by the MOT. Bikeviz are doing a pair of LED spots for either Hi only or lo only beam -

HongKong on ebay, could be cheap enough to warrant a punt.
