Daytime running lamps?

[bogan]

Reckon these could be a go, http://dx.com/p/10w-1000lm-6000-7000...-dc-12v-185685

What do we think?

Might be too bright, not sure on the regs regarding DRL brightness/beam pattern. I got some little Cree LEDs for work, 10V and 10W puts out 1000lumens, you have to see them to believe how bright they are, and then you have to wait a while to see much else

Well ive got a 1000lumen bicycle light, I was thinking of using them as spot lights at night as I ride a bit on country roads. Then get some small ones as DRLs.

If they are too bright at night, I bet there's a way to reduce the voltage for night riding. Does that work with LEDs? I'm not sure.

I'm running 12v 3w ones on the DR650 and TT350.
The TT is a 6v system and they run fine, just not as bright.

As Mr Popo said at a breath test (on the DR), "Wow those LED's are good"

[NordieBoy]

Are they these ones perchance? http://www.trademe.co.nz/Browse/List...x?id=602256633

I got a box of the 3w versions from China for about $8 a pair.

Yes, completely possible, but not very common.

Amongst other lights, I have these installed: http://www.clearwaterlights.com/infopg_krista.html

HP-LEDs that have a dimmer, which adjusts anywhere between about 15% and 85%. It turns the lights on and off many times a second, not noticeable to the human eye, but you can see on playback of videos. Turn the light down, and the amount of time per second the lights are off, increases.

$649 usd?

100mm by 100mm is pretty big...

I got these

http://dx.com/p/10w-950lm-led-warm-w...-dc-12v-185112

and they are huge... bigger than the size they say, twice the size of the cheap ones I use as fog lamps

http://dx.com/p/waterproof-3w-1000-1...-12-80v-179403

The ones above are quite cheap and nasty but work OK, I have another driver and chip to fit to up the wattage and have fitted a plastic lined lens to give a wide flat beam.

these are the day lamps I use...

The lights I have on the T-Sport utilise those little 12V light 'bulbs/units' that are about $9 for two at the Warehouse.

They are sealed, a flat face and have two pins at the rear that the wiring attaches to (i.e. no socket)

I think they are 40mm or so in diameter, mostly used as mini-spots in bars, shops and in some newer houses. (well newer than mine!)

Bright-as

The housing that these lights fit into were the expensive item.

Don't have access to offshore finance, the Kristas are a bit dear for me.

Sure, they're not cheap, but your question was, is it possible to dim LEDs.

Can they light up reflective boards at 2km on full power... Yes, that's also possible (and awesome)

Rheostat. Would that not work? House light dimmer jumps to mind.

Thinking about it, probably work for hotgrips to.

[leathel]

there are many circuit boards with 3-5 dimmer setting on DX.com for under $10 (Use a Momentary on switch to cycle through them), not so many in 12V, but there are some that drive an output of 4.2 V and enough amps to drive the tiny XML T6 chip that is very very bright or pretty much any Cree etc, I use that chip to spotlight rabbits and possums, no trouble to 200 yards and it lights reflective boards way way out there...Obviously with a larger reflector than you want as a day light but even with a 40mm reflector it lights up trees well.

I got some boards that have a single output to drive the replacement XML T6 to re-chip my current Fog lights

I just had a set of these arrive which look a bit similar. Not sure if I'll fit one or both. If they are bright enough to augment high beam I might try wiring them like so: switched by park light (for DRL)/off/switched by high beam. Will keep you posted.

I see the NZTA has proposed a change to the rules to allow for day time running lights, I started a new thread today on the proposed rule change...

[leathel]

I thought I might dredge this thread back up rather than start a new..... I fitted some LED spots on the fork legs of the 1100 and they have been working pretty well

http://www.dx.com/p/10w-950lm-cree-x...5#.U0JL2VemT-x

Some evening pics to show how they light up the road, I have fitted filters to give a relatively flat beam and tilted the spots down so they can be run full time on high or low like fog lamps (to light 15-20 meters ahead for big dip & pot hole spotting) and they have been working very well

The pics, the workshop door is 15 meters away.

Spots only, I should bend the brackets to get a wider flood as the overlap a fair bit.





High Beam (throws further than the spots but doesn't flood well)



Spots and high



Low



Low and spots



the spots only draw 10 watts each so I haven't had any battery issues at all to date
