Any idea why this might be happening? Might there be a problem with the relay?

Mine is a connected problem (I think).

After a longish highway drive at night when I use the stalk knob to switch off the HL they dont go off. :Shockked:

Happened twice. both times drove 10 -15 meters and repeated the operation of switching off and the stalk knob worked. Sticking relay? BTW Hella relay and harness and 90/100 philips essential vision bulbs.

It's definitely possible. I know that Fiesta's stock HL's are underpowered. It's true that using higher rated bulbs in the long run will eventually burn your HL's.

I had used higher rated bulbs before and now use HID's. I can definitely feel the difference. The amount of heat produced by higher rated bulbs is tremendous after long drives.

Since you are not looking for HID's, you can try out different brands that use stock wattage. Philips provides many options within this range. Although, you can find tremendous increase in visibility, this would feel much better than the stock bulbs.
Another option is to upgrade the fog lights since it wont get affected quickly when compared to HL's.

Higher rated bulbs will cost you around 1.2k which includes bulbs, relay, wiring. Stock wattage will not need extra relay.

As for the brand, Philips is always better. I had used Osram Cool Blue before.

For the fitment, you can approach any accessories shop in Blore. I would recommend "Sprocket" in Koramangala or Evo near Ulsoor.

Reason for not going for HID's?

Cheers.!

Naveen,

Thanks for the detailed information. No particular reason for not upgrading to HIDs. Not sure still if I will go for the upgrade. Warranty getting void is one reason. So thought its better not to overdo it :) The headlights need an upgrade and that very much needed, not sure why the company is not looking into it.

Also since this is some mod that needs to be done neatly, and I did not exactly had good experiences with the bangalore dealers during my sunfilm installation, I'm still giving it a second thought from where to do it.

Letme check with the places you have mentioned and ask them about the change. If they are confident with the mod, I will do it.

have you done this on your fiesta ?

It's its properly installed, it wont void the warranty. Since the wires are not cut, this wont cause any problem. I would also suggest HID's instead of Higher rated bulbs. Else, you can check Philips with the stock wattage. Some slight improvement, that's it.

Check these shops. They are good as far as I know. In cochin, you can check out Emperor. That's where I do my mods.

No mods in my Fiesta, only Swift.

Cheers.!

Looks like you've got 2 relays connected. I faced a similar issue sometime back.

While upgrading from stock HLs, most guys suggest adding a relay WITHOUT checking whether the car has Relays, If there are 2 relays acting, then this problem occurs..

Pl check your electrical circuitry!!

AFAIK no relays are required for stock HL view their lower wattage. relays are added for the 90/100 W. Thus how would 2 relays be connected? My circuit is very similar to the one below. [IMG]file:///tmp/moz-screenshot.jpg[/IMG]

Yeah, sure will check out the shops and the options you suggested. Will update if I go ahead with any changes.

Would like to upgrade to HIDs, but since I dont know a thing about the circuits or installation or anything, wasn't very keen. Anyways letme chck with these guys and see what they have got to say.

Any specific good brands if I'm planning HIDs ?

Philips is always good. But it's very hard to find 4300k HIDs since they stopped manufacturing them sometime back. But if are lucky, you may find their old stock. Else, you will have to go for 6000k. Keep me updated. All the best Dude.

Sir, MOST new gen vehicles come with OE relays for HL even if it is 55/60W.

I HAD the SAME problem in my vehicle and discovered that OE relays were fighting with the newly installed relays. Hence the suggestion!

And relays are good even for lower wattages!!!

I have an old pair of Hella Rallye 1000 mounted on our family Omni. I would now like to remove it and install it in another car. I dont want to use the same old wiring harness / relay / switch kit and I am looking at buying a new set - just the harness / relay / switch.

Am in Chennai and I checked with Haute Car Zone as they are supposed to be authorised Hella dealers. I was told they dont sell harness kits separately.

I also looked online if genuine Hella wiring harness kits were available, am unable to locate a Hella genuine Rallye 1000 kit.

What are my options? - any guidance would be helpful.
I also saw on Amazon that a complete wiring harness / relay / switch kit is available for Rallye 4000 - can I use the same kit on my Rallye 1000?? - sorry guys, am a bit of a noob when it comes to electricals, hence the question.

If u add one more relay the OE relay will be almost free of load (say 1% load) as its driving the second relay's coils only. Now the bulb load is totally borne by the second relay which is the best at least in case of vehicles under warranty. Every car HL relay is rated to 60W bulb as 55/60 is the commonly used even for 3 wheelers. So if some one is planning to upgrade to a higher rated bulb only go for the extra relays. As long as you are playing within the stock range you are safe with the OE relays.
