simonjrwinter Posted April 12, 2016 Report Share Posted April 12, 2016 I've bought some better bulbs as advised. I now intend to fit relays. Do I fit one relay for the pair of low beams and one for the high beams? Quote Link to post Share on other sites
rogerguzzi Posted April 12, 2016 Report Share Posted April 12, 2016 (edited) Yes and seperate fuses then there is no strain on the main switch or dip switch Roger ps go for the 30amp relays(a bit over kill but safe) Edited April 12, 2016 by rogerguzzi Quote Link to post Share on other sites
Austin Branson Posted April 12, 2016 Report Share Posted April 12, 2016 (edited) +1 for separate relays. I also wired mine so that main-beam selection switches on both the main and dipped beam filaments. Not illegal. Austin Edited April 12, 2016 by Austin Branson Quote Link to post Share on other sites
John Morrison Posted April 12, 2016 Report Share Posted April 12, 2016 Nope. one relay per filament i.e. two for dipped and two for main beam, that way if the relay fails you don't lose either all main or all dipped. John. Quote Link to post Share on other sites
RogerH Posted April 12, 2016 Report Share Posted April 12, 2016 ..or one relay for dipped and one for main and carry spares........ Roger Quote Link to post Share on other sites
barkerwilliams Posted April 12, 2016 Report Share Posted April 12, 2016 (edited) Simon, Do you have a radiator fan with a relay, a fuel pump with a relay etc? Could I suggest that whatever relay(s) you choose for the headlights is of the same type and rating, then you only ever need to carry one spare.

John. My goodness thats like catching the bus before the bus before the bus so you are not late? You could use these sort of relays. http://www.ebay.co.uk/itm/221289619616?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT Thats the type I used on the electric fan but not on the headlighs I used a seperate fuse box as I wanted extra fuses for the Megajolt ignition and electric fuel pump. Roger ps just ordered 2 of these thought it wise as I have 4 on the car now! and even if not the best quality they are not worked hard(10/12amps) http://www.ebay.co.uk/itm/111581062672?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT Edited April 12, 2016 by rogerguzzi Quote Link to post Share on other sites

ShaunC Posted April 12, 2016 Report Share Posted April 12, 2016 +1 for separate relays on dipped and full beam. I would avoid powering both filaments on full beam use, the additional heat may shorten life and possibly impact the reflective surface on the light holders. Although, if usage is low you could argue that it's not really an issue. Fit some good quality lamps with good light output. Mine are Philips which have quite a white light, may have been their +130% type. I've wired my Lucas spots to come on via a separate relay with my full beam, 4 lamps that provide huge amounts of light. Quote Link to post Share on other sites

I didnt bother with relays for the headlamps but I did add them for the future fog and spot lamps and I put them where they would be largely out of sight but still accessible if I needed to swap one out.

Steve P Posted September 10, 2016 Report Share Posted September 10, 2016 Morning Gents, I'm looking at doing a headlamp upgrade. I'm going to purchase the Moss relay kit. Can anyone advise a bulb part number that is a direct replacement for standard? Thanks Steve Quote Link to post Share on other sites
peejay4A Posted September 10, 2016 Report Share Posted September 10, 2016 Any H4 bulb should do the trick as long as you don't have ancient BPF bulbs or sealed beam units. I and others use Osram Nightbreakers - I think the latest version is called Unlimited. Quote Link to post Share on other sites
RogerH Posted September 10, 2016 Report Share Posted September 10, 2016 (edited) Hi Folks, it is amazing just how different H4 bulbs can be. The standard H4 glows and illuminates the road, to a degree. and uses about 5 amps. Xenon bulbs are a great improvement. Still use 5 amps but you can see far more. Halford do some 'extra' powerful ones and these are very good - still with 5 amps. I haven't tried the 'Nightbreakers' yet and they sound very good. However I fitted a pair of Philips Supa Dupa really bright SuperNova's the other week and these are stunning - still only 5 amps (X-treme power) But. I can't remember where I bought them from. Compared to the HID units I think they would hold their own on any country road. AND they do NOT blind the on-coming traffic.

TriumphV8 Posted September 10, 2016 Report Share Posted September 10, 2016 It is so easy: No need to use illegal bulbs and those HID scrap. Simply measure the voltage at the bulb and you will see the possible improvement with relays and direct lining of the 14 volts from the alternator to the bulb! Simply light the bulb in the evening and watch the glass. Often there are little bubbles enclosed that make the glass shine like mist. That is the light power that is lost! So I simply recommend to use the Hella glass &reflector as a direct replacement for Germany. Do not know if the provide that for right hand drive but its worth a try. They are simply perfect! The Range Rover clear glass ones are also very good but give our TRs a much to modern look and I would not recommend them. The OSRAM night breaker bulb is also my first choice.
