LED H4 is just a fancy light which can be used as DRL (Day Time Running Lights). It cant be used as Headlights as the intensity is too low to light up the surroundings.

This H4 LED is a joke. Please note that your reflectors for the H4 bulb are made with a near point source of light being at the design stage. Even the slight spread of the Plasma source in the HID bulbs plays havoc with lighting when retrofitting HID bulbs in normal reflector assembly's. Thats why its nearly impossible to get a good beam spread in a HID retrofitted reflector assembly without subjecting oncoming traffic to glare.

thanks,

yes, for sure over a period of time which depends on the quality of the reflector , first they fade to yellow, loose thier sheen and then they start to blacken out , on my car the headlights are a visibile fade yellow by two years of use with extensive night time driving.

thanks for the response. my daily night drive is about 1+ hours while returning home, mostly having traffic. lets hope it lasts long. btw, not sure if only the glass / reflector would be available (without the entire HL assembly) ?!

There are no aftermarket projector kits availble for Linea yet. You can retro fit projectors onto the existing headlights but that will be expensive and you need to have a very skilled mechanic for that.

Else, you can check out HID's but these are expensive and I generally dont recommend HIDs on stock headlights. HID's are meant to be used with projectors.

Hi Naveen,
Yesterday I had a chance to visit Jiwaji, Chennai with my friend to change the stock bulbs. We replaced them with 100/90 and the result is as expected. When I asked Jiwaji to replace my Linea's stock bulbs, he clearly said there is no H1/H7 100/90 bulbs in the market . Is he right?

Cheers
Kumar

I believe he is. Based on what I know, max you get in H7 is 80W. This is in Philips and Bosch bulbs. Also H1/H7 bulbs have only one filament, unlike H4 which has 2 and hence called 100/90 in which one is high beam and other is low.

The H1 is available at 100 watts so in effect in your Linea you can have 100/80 though with two different bulbs since as pointed out H1 and H7 have single filaments in them unlike H4 which has 2 filaments. For the Linea though I suggest you use a relay for the 100watts bulbs and make do without relay for the 80 watts.

Fiats are not very well known for their electrical wiring after TATA took over some stake in the company even if its just sales.

Thanks Doc, this is good to know. I was aware H1 and H7 are of same size so can be used interchangeably. I guess the only diff is black tip. I was under the impression that H1 is mainly used as a fog bulb, so should be available in less wattage.

OT - thanks for your help on the diesel engine oil suggestions. My car, after the oil change is much better than earlier. Not as though as it was when new.

Both are Head light bulbs, both are used for headlight, foglight and driving light applications. H1's and H7's have a different filiment lengths, so will create different light patterns in different HL housings. Since they are entirely different its not interchangable, and HL housings are designed according to the mounting bases and the filiment length and orientation which plays a major role in beam spreads. H1 is considered to be high beam universally and most of the projectors as well.

Take a look on these

Hi - Does anyone here use KC Daylighters/Hilites? -Any observations on them?
I am tossing up between driving lights and long range pencil beams (130W).

Any feedback on the same would be appreciated.

Personally, I have tried the long range pencil beams but found them inadequate for road use, especially in todays roads. [my grandfathers Rover 14 had it and I was gifted the same for a fit on my GYPSY, decided against it after the use i put the gypsy to, did not want to break the glass of the original LUCAS unit]

I'd go for driving lights instead of pencil beams!

Thanks sajjt. I was looking for their HID sealed beams and I guess it is better to pick then during some trip abroad to save on customs duty.
