What are people's thoughts on them, I quite like the look of some headlights I've seen on bikes I've passed on the street, they're so nice and bright. Just can't seem to find anything about being able to fit them on my ickle 125.

I'm not mechanically gifted enough to consider LED indicators yet because of the relay change which just totally baffles me.

Just gauging what the opinion are on them

Do Not Want!

LEDs are a nightmare environmentally too and throw off weird light wavelengths....

As was designed to fit the bike. Cheap ebay tat is likely less visible than stock or will have worse beam pattern. Indicators are a major pain in the ass as you either need a flasher that can do LEDs or to have load resistors which just eat the energy LEDs save. Converting a single H4 headlight to LED usually goes badly. Try osram nightbreakers or phillips xtreme power bulbs.

I did run LED spotlights though, one pointed very low and left as dip supplement and the other wired to come on with main beam. Ten quid lights of ebay did the job.

21w incandescent indicators, with a good polished reflector work well. Ive not seen LED's as good.

LED running lights on mirrors, handguards, luggage, anywhere that makes the bike look wide are good things to have if your fashion sense can stand them. Make sure you don't distract from the brake light.

If they came as standard, yes. Otherwise only as auxiliary items that won't affect my normal running lights.

Don't put a LED bulb into an incandescent housing. It's less of a point source and the beam pattern will be all over the place.

Auxiliary LEDs, sure, the more the merrier.

Some bikes ive seen where i live look good, the owners have gone with the idea that its safer to be seen.

However there is a fine line between a few extra lights for safety and going too far and looking like a mobile Christmas tree :/

would i put some on my bike?.... probably not at this time.
I wouldn't rule it out if they was easy enough to fit without changing too much

You don't need lights for that. Whistle

I bought a pair of red LED tail lights for the dirt bikes recently,mainly because the alternator output of the XR is only 80w and I need the power for the 35/35w headlight and the AC horn

https://i666.photobucket.com/albums/vv23/WiNot_Rhencullen/Workshop/20151231_115042_zpsb84rthjr.jpg

But they looked a bit flimsy and may well be a bit prone to vibration,so I filled the gaps with clear silicone

https://i666.photobucket.com/albums/vv23/WiNot_Rhencullen/Workshop/20160119_100204_zpsz5dckdit.jpg

They work quite well Thumbs Up

if the bike came with LEDs then fine

otherwise I stick to bulbs, rather be seen then have tiny led indicators which make the bike look nicer!

Ergh! The LEDs through the housing look like a UFO.

So does that mean on some of the newer bikes I see that have that sort of white/blue light (which seems to have become the norm on new cars) are actually not LEDs but just higher W bulbs?

Definitely help with being seen that's for sure!

Replaced mirrors with ones that had light fittings. Replaced regular amber lamps with white LEDs. Wired as DRLs.

Replaced rear light with an LED unit

I'm mulling LED indicators but only if I can find properly bright, wide-angle ones. Sort of thinking about LEDs for instrument lighting but so faff. I will not use an LED headlight bulb because the headlight reflector simply isn't designed for it. I am daydreaming about a retrofit HID projector set-up, but there's plenty else to do first.

Interesting. Thinking

My DRL LEDs have a tendency to drop chips and components off of the circuit board, presumably down to vibration. I would be worried that if I siliconed them they might overheat... no?

All of them.



They're not actually as bright as they look in that arty shot, but they are visible.

2 x 30cm of these: https://www.ebay.co.uk/itm/291471117732

1 x https://www.ebay.co.uk/itm/301331075447

1 x https://www.ebay.co.uk/itm/111581062672 (I put a spare 5A fuse in it)

I bodged the relay into my dipped beam circuit using a splice connector that I had to hand. https://www.ebay.co.uk/itm/391224472873 That's the lazy and probably failure prone way to go about it, but I didn't have much wiring or access to play with, and you can't go too far back into the CANBUS wiring on the Beemer. Works for now.

There is some difference,but not that easy to differentiate from the side when operating the back or the front brake on the KTM.

I have just bought some new hydraulic brake light switches for the XR as the mechanical ones have packed up.As the tail light bulb is mounted completely differently it should make it a more worthwhile modification.

There is little or no heat given off by the LEDs compared to a glass envelope bulb Idea

Yep, here's mine (I did it to reduce the draw during braking which affected my headlight, it solved that. I might gonna need to rebuild my alternator. Thinking - BAY15D 6W 600lm - £4.10 for a pair):

By the way, 600lm is equivalent of a ordinary double filament bulb. I tried 400lm but it was way too dim to be safe. So, if you decide for LEDs go for 600lm+.

True, but they do give off heat and overheating is a common cause of failure.

All of them, the only incandescent bulbs on my bike were the rear indicators and high beams so they've been changed.
Rear indicators replaced with Panigale 899 led ones.
High beams replaced with H11 led because the normal bulbs were crap, the high beam was no higher than the dipped beam so pretty useless, the LED's have raised it and made dark country lanes much nicer to ride down.

If the dipped beams were incandescent then I would probably not have fitted LED replacements to those because they would have destroyed the beam pattern.

I do not think that 85mw is going to melt silicone

As for heat causing LED failure,I have very rarely experienced this in the 35 years that I have been in the electronics industry.
