Re: K5 Pointy Headlight Connector Burning out
Good job, what LED lights did you fit ?

Re: K5 Pointy Headlight Connector Burning out
Installed these:
https://www.amazon.co.uk/gp/product/...?ie=UTF8&psc=1 Wanted something kinda cheap to see if led was a viable option, but actually surprised at how good these things are. Mega bright and a good temperature. Only time will tell how long they last I suppose... |

Re: K5 Pointy Headlight Connector Burning out
Look good but Id like to know how much less current they draw than conventional bulbs because of course this difference in power consumption will now have to be dissipated in the reg/rec unit so possibly leading to an increase in its running temperature......

Re: K5 Pointy Headlight Connector Burning out
according to the box they are 48W, which would be 48/12 = 4 Amps per bulb. A normal SVs bulb is a 60/55W so on low beam 55/12 = 4.6 A per bulb.
The bulb will run much cooler but the LED power supply will still be producing heat (and requires a built in cooling fan). Not a big drop in current but much more light, the only problem is that a vehicle headlight is parabolic with only one focal point, if the LED is a stack of small diodes they won't all be in focus wasting the superior light output. If it's a single LED and set at the correct height it's death rays 'r us. At 6500K (Kelvin) it should be quite a blueish light compared to a stock bulb. Last edited by Seeker; 03-10-18 at 07:14 AM. |

The reduced draw will affect RR power, especially with twin headlights and you only draw 4 amps instead of 10 with a filament bulb. For some unexplainable reason the ones the original poster has fitted have one horizontal and one vertical LED array - that looks like no H4 bulb I have ever seen ( there are two horizontal filaments with a 'cut-off' shield below the dipped filament https://en.wikipedia.org/wiki/Headla...4_IMG_1269.JPG ) if you look at the bulb in my classiccarleds link the LED exactly follow the filament H4 placement. Would be interested to see the beam pattern on the OP headlights, may not pass and MOT with them in.

Re: K5 Pointy Headlight Connector Burning out
If anyone is concerned about the extra heat that may be produced at the R/R they can do what I did when I recently repaired/upgraded my R/R to a Mosfet one.I basically over-engineered it by adding a small cooling fan.It runs off the thick Orange ignition switched wire under the fuse box on my Curvy.
http://puttingoutfires.x10host.com/M...Rpictures.html I think there would be enough room under the fairing for it on a Stock R/R as I had to move the new MOSFET R/R to the left hand side of my SV because of the original Bracket on the right and the size of the new R/R. Although I don't have an LED headlight bulb/s I have replaced my rear Stop/Tail bulbs,Number plate and front parking light bulbs with LEDS. The position of the Fan on the MOSFET R/R was chosen using my Heat temp gun and was the main heat area on these. The fan cost £1.99 and a few other cheap bits like connectors and an in-line fuse holder. I also fitted a cheap LED Voltmeter farkle on my handlebars to give me an indication of my running voltages which after the repair are now back within spec. HTH

Re: K5 Pointy Headlight Connector Burning out
I supposed it's obvious but I'd never given it any thought that you can get vehicle lights that are illegally bright. I looked at the Philips Ultinon X-treme and they are not road legal, I suppose the name is a clue.

Re: K5 Pointy Headlight Connector Burning out
on a twin headlight jobbie looks like about an extra 85w has to be continuously got rid of in the RR....

Re: K5 Pointy Headlight Connector Burning out

A car alternator has a field coil (instead of a permanent magnet) whose magnetic field strength can be adjusted to reduce the alternator's output when the demand is low. The early Hinckley Triumphs used a car style alternator but they are bulkier. So switching to LED's may reduce the current flowing through connectors at the handlebars (not by much in this case) but the r/r will run hotter. Ideally, the high current devices should all be on relays so low power through the switch gear and the lights (for example) are on a separate, fused supply from the battery. |
