Why no HID for highbeam?

ceecookie SG

Is it true that HID is only for low beam as its design is meant for long period or usage and not quick periods like flashing?Doing so will shorten the HID buld life...

Is this all true?
any other reason?

Why use HID for high beam?
I using 6000K HID for main beam... In Malacca, when raining, next to useless... thank god i kept my high beam yellow...
but normal NS highway in the dark, the 6000k Main Beam damn shiok liao... as long as it don't rain or fog...

bo liao SG

hmm..dun tell me u the person at ST Powered taking the hid to exchange & write to japan?

nope. it is just tat if ur car was not originally fitted with one, it is not just illegal to do so, but to do it recklessly will result in fire. y? cause the cables intended for the normal halogen lamps can survive 55W but HID goes some 70W +, this will cause cables PVC to melt and short together.

to fit HID aftermarket, you need to replace all wiring, etc. a major project. so dun pray pray with ah beng contractors.

Haha, like I said, HIDs are only allowed to be factory fitted.

As for High Beam HIDs, LTA don't want you to be a guailan-kia and start flashing other drivers as it may cause distraction to them (Although you can do that with the freaking tall RX-300). Honestly, HIDs are cool, but it only works best for City situations. And LTA really care about other drivers, ma.

I also want High Beam HIDs. =P

Not true. Odyssey has a HID main beam and a halogen high beam. Its like comparing.. a bulb lamp and a flourescent lamp. Long period and flashing will not affect the HID in any way.

The main reason is that LTA does not see any reason for you to require high HID in a city area when a halogen is enough. And because HID may blind other drivers due to the high Cd of output light.

The exact reason is that HID operates via a ballast, which means to say, it takes some time to get started up and warm up to the temperature. If you notice cars with HID, the moment they switch on their HID, it will take a while to light up and achieve the intensity. Which means to say, if you install HID on your high beam, the moment you activate in emergency, e.g. to warn someone not to cut into your lane, it will have a retard reaction. So the guy in front will not see your high beam, and you’ll cursing and swearing ‘cos you run into him.

I thought because of that problem, they use Xenon for HIDs to counter the problem of the voltage arc establish?

actually i read somewhere that increased frequency of turning a HID on and off reduces its lifespan more than just leaving it on. I mean its quite common sense, the action of switching on and off causes some wear no matter what. right?

ceecookie SG

but i tink the wear and tear for the HID if used on and off is more significant compared to other lights.......

In the 1st place the purpose of flashing a high beam at on coming vehicles is not to warn them that you are coming. This practice is REALLY ONLY SEEN IN SINGAPORE.

I've lived 4 years in UK, flashing of the high beam means telling the other driver to move on hence in some motor bikes you see the button for high beam is actually labelled "PASS". Laughing
