I have been blinded many times, on a daily basis. I have always presumed that's because the other party is on high beam. | Quote:

The Ecu was cutting the power supply as it was of higher wattage(55W) and the OEM bulb wattage was 35W and hence i decided to put a switch. boy i am not disappointed at all.
i installed the HID as i am planning to go on a holiday and do a lot of travelling especially highways. i did the install in Power Zone, Royapettah.
i am very satisfied with the HID in my fogs. i have seen many scorpios here in chennai with HID in fog lamps but it was 6000K or more. it was mere bling and no performance.
so i took the plunge and am not disappointed at all.
ill let the pictures do the talking. |
HID bulbs are arc lamps. Unlike halogen lamps that give out light along the length of the filament, the HID bulbs give out a point source - that too about 3 times brighter than the corresponding halogens.
The stock reflectors are not designed to reflect such kind of light.
So what you end up doing is just creating a LOT of public nuisance due to the glare created by these lamps. When you install these kind of lamps, I urge you to give a thought to the poor guy in the oncoming traffic who is getting insanely blinded due to your vehicle's glare.
The glare is painfully evident in the pic posted by you..
HIDs are meant to be put in projectors and not in reflectors, so spare a thought for others as well. Quote:

Also mention the respective prices, if possible. Thanks in advance. |
Roots and Minda have decent harness kits. Just ensure that you make a few cuts / holes in the wiring conduit (the flexible plastic hose enclosing the wires) to let out any water that gets in. Quote:

Now, The positive and the negative terminals of the kit are directly connected to the battery terminals. I asked him why this is done since this way is bypassing the fuse whatsoever, since Minda has just a relay kit , not a fuse ( I understand...pls correct if I am wrong). He did not say anything apart from that usual way ' saar ,its done in this way in all cars , so its a correct practice' .

In cars, earthing and negative are the same thing (ground), so if he has connected a wire of the harness to the battery -ve and has also connected a wire to the car's body frame, I am a bit confused.
The harness has a relay. This relay is driven by the signal that is coming from your car's current bulb connector. The relay connects the battery supply directly to the bulb when you switch on the lights.
Ideally, for a 100/90 set, you should have around 15A to 20A fuse (abt 7.5-8A each bulb at 12V) connected between the battery's +ve terminal and the harness. The fuse should already be there in a Minda harness, but if it is not there, you can purchase one and connect it in series.
You can get it from the same Lucas fellow or Satish Auto (probably the same guy) or at auto shop that is just below SBI (near Big Bazaar) at Chinchwad.
