Honda Jazz Mk3 2015 - / Re: Main Beam Assist

These have not been my experiences with the main beam assist on my Mk 3 Jazz.

As I say, some systems might be better than others, and I have no experience of the Honda system. I'm all for driver aids, but I'm just not keen on the system fitted to my Vauxhall.

That said, culzean's point is still valid - there are instances where a considerate driver would dip before seeing the oncoming car's headlights, rounding bends, brow of a hill, etc., and these systems don't, as a rule, dip lights until it recognises the headlights of the oncoming vehicle.

Shocks should always be replaced in pairs

Monroe and kyb are some that come to mind, there are others I am sure someone will mention

I would replace as an axle pair, unless nearly new and you are replacing one like for like. Avoid no-name and cheap brands you have never heard of, they don't last. Fit a known brand such as Kayaba (KYB), Sachs, Monroe, etc.

Can't help with dealer costs, I only use a garage for my MOTs, but rear shocks is a straightforward job that any competent garage should be able to do while you wait.

I turn my main beam off the second I see lights approaching, probably long before the auto feature would. Having spent a lot of time commuting on unlit B roads my pet hate is dazzling headlights and I give others all the courtesy I can.  Your sensors don't know if your lights are dazzling oncoming driver, and leaving mains on longer does not sound good to me.  This sounds like another ' auto ' feature for drivers who are not paying attention.

Having now had a car with this feature, I have to agree 100%.

I thought it was quite clever at the beginning, but after a while it became apparent that there are many instances where the forward facing camera cannot see oncoming headlights clearly, but the oncoming driver would have a direct line of sight to your full beam. I mentioned the issue with lorries and dual carriageways earlier, but there are other examples, even gentle bends and a low hedge or bank can leave you blinding an oncoming driver for a considerable time. Not only that, the HID lights fitted are extremely bright on full beam, it's like broad daylight, and carry for some considerable distance.

Even when a car rounds a bend in clear view, there is a short period when the driver is dazzled before both headlights are pointing towards you and the system recognises it as an oncoming car, and motorbikes are not always seen. I would have dipped much earlier in most cases than the car does.

It can also be fooled by tail lights too. With cars, it's generally very good at spotting them at distance, but it also insists on dipped lights whenever I'm driving towards directly at of the local power stations, which have red navigation lights up the chimneys. You see multiple pairs of red lights in the air on the 600ft stacks, but the car thinks it's another vehicle, even a mile or two away.

I mostly switch it off now, but the car turns it back on if you stop and restart the car. Maybe some systems are better than others, but if I could turn mine off permanently, I would. The other bits such as side lighting, auto lights and adaptive beam work well, but I don't like this main beam assist.

I think you'll be OK with car polish - especially something like Autoglym Super Resin Polish as recommended by Culzean. I have seen a number of videos of people trying to restore cloudy headlight lenses and the stuff they use (seems to be a form of wet sanding) is vastly more aggressive.

Back on topic, I've not noticed a problem on the Jazz with light reflected from road signs.  I don't know why not - could it be something to do with reflected light being polarised?

I also noticed that the Jazz can tell the difference between reflective red marker posts and tail lights.
Yeah the main beam logic is pretty good. I'm not convinced that it sometimes gets it wrong. Just because a vehicle is in front of you doesn't mean that it's being dazzled. The main beams have a particular pattern and if correctly programmed the car could leave the lights on longer than a human would because the car knows it's not a problem.

I'd put the main beam handling forward as an example of good automatic technology.

I clean my headlights with AoutGlym Fast Glass and the result is quite acceptable.  The guy next door cleans his with car polish,.  His headlights look good, crystal clear and shinny so I was tempted to polish mine but I wonder about the long term effect.  Is car polish  good or detrimental  for headlights?

I have used auto glym super resin polish on headlights for many years and it keeps them in good shape.  The clouding of plastic is a combination of environmental pollution, ultraviolet light from the sun and heat from filament headlight bulbs. The autoglym cleans off the film of pollution and leaves a layer of sunblock behind, and our cars now have LED headlight bulbs reducing the heat by 90% ( downside is they don't melt ice and snow off the lenses ).  If you lights are cloudy use fenwicks caravan window cleaner ( from Halfords or t'internet ).

Been advised I will soon need a new shock absorber as it is leaking (rear). Should I replace the 2 at the same time?

Any estimate of Honda dealer costs?  And what make do Jazzers recommend?
