Recently I heard that LEDs are not good for your eyes. Even at home, we should avoid looking into LEDs directly. I dont know will it be useful for this discussion, but thought of sharing the info I heard.

Even I have LED cabin light and parking light for my sparky. Planing for LED reverse light and red light in LED for my sparky.
That's interesting, haven't heard that before...any idea why so?

I hope you don't mind my asking, but did you buy the LEDs online or in a local auto store?

I do not know the reason. Just heard the news some time back in some tv program.

I bought it in local store. Cabin light i got it fixed by the store wala himself. But parking light I fixed it myself. I will post the pics later.

As far as I can figure out it's because the LED is a point source of light so is very intense relative to others like fluorescents.

Ok...thanks. I have interior dome light LED panels too actually [:D]

What experiences do you want to know about?

Agreed! And since fogs are aimed low and wide they are actually less disturbing than regular low-beams to other users!
By city lights are you referring to clearance lights or low-beams?

Actually that makes sense to me, fogs and high-beams should never be used together:

In foggy or dusty conditions the high-beams will just backscatter and blind you.

In clear conditions fogs help short-range visibility, but if you're using high beams chances are you actually want long-range visibility.
1)By City lights, I mean those very small 2W or 5W bulbs . They don't offer illumination but just say "Im here!" on completely dark streets.

2)I do not agree. Many of the folks have come to me to learn how to defeat this stupidity. What happens is, when we Engage the High beams, We completely miss out Closeby illuminaton.This is especially true for H4 lights. It casts a huge shadow upfront the car and is very risky. Turning on Fogs along with the High beam fills the shadow and provides even light. Its also easy on the eyes as we do not have to adjust from dark to light areas so often.

3) Agreed, Experts suggest using LOW beams+ Fogs in Fog and rain. Not high beams. That's what i tell everyone to do.
My few paisas on this LED and overall after market headlights etc matter.

LED's in India have become more of fling thing. IMHO it is not adding any value(read LED's such as in i20). In Sweden they are compulsory as there is hazy atmosphere and low visibility. To increase visibility they were added as must.

Overall comments--
While designing headlamps OEM's take into account the temperature generated by headlights and design the assembly accordingly. However adding aftermarket LED headlamps, HID's and etc, the increased temperature always make headlamps dull.
I have seen such after market lights make the headlamp assembly dull further reducing the effect of headlights during night travel.
1) The fling Thing yes. Thats due to the teens taking their "COOL" car out, and buying the Cheapest and most Obnoxious LED products on the market. We can't blame the tech for this. Look at Audi R8 All LED headlamp and you'll see what quality, legal LEDs mean.

2) Even though we don't have LED DRL laws in India, i will still recommend them as people seem to noice the car better and their response is better. I have installed LED DRLs on my wife for the very same reason-safety.

3) HID and LED DO NOT generate any more heat. Actually they run much cooler than others. Its the ugly 100/90W bulbs that cause the problems you've mentioned. However, stuffing LEDs into Housings Made for Factory halogens WILL cause all sorts of optical problems and poor focus.

Recently I heard that LEDs are not good for your eyes. Even at home, we should avoid looking into LEDs directly. I dont know will it be useful for this discussion, but thought of sharing the info I heard.

You're talking about Bare/Open LEDs. Use products under proper Lenses/Diffusors and this problem shall vanish. LED provide very concentrated light so the reason

Stay away from LED reverse lights, They are not Legally aproved, and usually lack the amount of light for safe reversing.

I thought reverse light will be working only at the time of we reversing and do you still need approval for this? And i have reverse camera (screen stopped working and am planing to buy a small 3.5"/4" LCD screen for it soon) so I thought it will be more useful. With current ordinary lamp I found it is not that useful in nights.

The Normal CORN type Bulbs you buy are in the Range of 200~400 Lumens.
Your Factory Lights are somwhere like 500 Lumens.
If you want a decent improvement, Aim for atleast 1000 Lumens. I've seen where people Have added headlight H1 or H8 Bulbs in reverse light housings. Super Cheap, Super Bright.

Wow, That is nice option. I am planning for 90/100 bulb in front (head lights). In that case i can switch the existing 55/60 bulb in rear. But the setup in rear is suitable for that upgradation?

the risk won't be high as reverse would be engaged max 30 sec, right?
if you can get the holders right, it shouldn't be a problem.. else, I'm against 100w bulbs in the front. they're damaging to the vehicle and also blinding to oncomers.

Ah right, I call those clearance lights.

Even for H4 bulbs, if the high beam leaves a huge shadow it's usually due to misadjustment from switching bulbs without adjusting the aim for the new one. Typically the shadow from the high beam is small enough to be unnoticeable when you're moving at some speed, which is pretty normal for a situation where you would be using high beams.
I'm just saying I have never encountered this problem in any car before. This is a potential issue with taller cars like Landcruisers but in those when you turn the high-beam on the low-beam stays on as well.

Yep, exactly. I told a Rajasthan Roadways bus driver that once and he just gave me an unbelievably blank stare [frustration]

In most of the cars i've driven are plagued with the shadow problem. To make matters worse, even my XUV 500 has Upfront shadows in LOW beam as well! I had to ammend the same using some LEDs. Pictures are in my Thunderbolt 500 thread.

Hmm...that's a bit odd, have you tried adjusting the beam to overcome it?

I guess they didn't account for the added height of the XUV when designing the housing, I guess LEDs can fix everything though. [;)]

when I set them lower, the cutoff falls just at 20 feet. when I bring them up, cutoff moves to 60 feet but shadow rears it's ugly head. check the pics and you'll understand.
