LED lights...

Can be used as FOG lights

I am interested in any LED lighting. But what I really need at the mo, and cant find at any price (despite the fact that several US suppliers claim to have them) is a pair of LED rear Fogs.

You can use these as fogs if you like, just wire the 'brake' wire to your fog light switch rather than the rear brake.

So far I have one provisional order for the red from DaveGSCymro prices and turnaround time soon...:)

Coolcarbon, I will have a look at this later. The design is not a problem it is making the circuit board to fit snugly into the housing..
 
Prices

After a few calculations and based on the small amounts requested, they are going to be £20 + postage per pair of either white or red.

This is £9.99 cheaper than the light buddies offered by Nippy Normans and these have two intensities not one and they are available in white... :)

If I get more people wanting them then the price will drop because the more bits I buy, the cheaper they are. Though it won't be massive unless we are talking hundreds.

They will come with 2x50cm of cable to connect to the lighting circuit and a shorter ground cable to connect inside the indicator housing. They will be backed by tape with a small plastic sleeve under to prevent shorting on the indicator housing. I mount mine with bluetac to hold them in place while I get the lens on - haven't had time to find thick sticky pads, but to be honest, the lens holds them tight so you shouldn't need anything else.

Feedback welcome if you buy any.

Been out today with them on and had a lot of comments on them. Also finished the rear led light prototype, looking good. Got to go out later but will try and get a photo on.

Techno, put together a pic of what people will actually be purchasing and then the results they will be achieving as a result.:thumb2


Will do. Just got to go out for dinner now so am being dragged off the computer. Probably tomorrow night. Have a look at pics earlier on in this thread.

I have also made an LED tail/brake light unit for the 1150GS

I would be very interested in this please let me know when you have price ect:thumb2

Cheers :beerjug: Steve
 
What LED die are you using? And how are you controlling the current through them?

PM me the details and what you pay for them if you want and I'll see if I can get you them cheaper. I've become a bit of an LED geek recently...

The LEDs are ones I found after hours of research! For the quantities I am buying I cannot command a cheaper price. Cheap LEDs are always available (generic 3,5 or 8mm ones), but these are designed for automotive use so are more expensive :(

Current limiting is done with resistors. Limiting current using transistors as a constant current source is not a good idea in this design (simplicity) but if you were using high power LEDs it would be (I think that is what you are thinking about when you say LED die.)

What they look like...

Ok, so here is what they look like.

You get 50cm of wire for each side (which will be of a different colour to that shown here) for brake and tail and a short piece to ground on the indicator. Some heat shrink over the cable to to prevent chaffing will be added. Connectors are included but you have to crimp these after or you can't get the wires through the holes!

I have fitted mine with a bit of blutac (how unprofessional) instead of a sticky pad. Doesn't move once the lense is on but allows adjustment.

Fitting is very easy. NO SCOTCH LOCKS, NO CUTTING

1. Take off the indicator and rear lenses.
2. Remove the indicator reflectors
3. Remove the rear light reflector (2 screws)
4. Feed the LED wire through the indicator holes on both sides so it falls out behind the number plate.
5. Push these two ends through the rear light cable entry grommet (bit fiddly this bit)
6. Connect the tail and brake cables from the LED to the rear light using the connectors
7. Connect the ground cable to the ground in the indicator housing
8. Test all is working.
9. Replace reflectors and stick LED modules to indicators (making sure you can get the lense on!)
10. Replace reflectors and lenses, zip tie cables to number plate housing leaving sufficient slack
11. Congratulate yourself on a good job and go for a ride.


Need more detail than that?

New design is slightly smaller (17mmx35mm). From what I have tested the reflector is non conductive, but I will still put tape on the rear.

Project R just do the lense for 28.99 then upgrade to LED for 11.99. Doesn't show what it is though - might just be an LED bulb like the types on ebay. Got anymore info? No point re-inventing the wheel.

Anyway, this strip to put into the indicator not an indicator replacement. Is a running light brake light and/or fog depending on how you wire it.

Will do the 1200 ones soon, but need an inticator to check sizing.

I fitted one of these from the supplier mentioned above and it seems really good. Very bright and visible from the side. Has 27 LED's in all. I hunted around on Ebay and got a 2 pack for £10.00 delivered which is not a bad price from http://www.project-r.co.uk/bulbs_and_flashers.htm :thumb The bulb just replaces the standard stop and tail bulb. It's a type 1156 bulb I think for the 1150GSA / GS. There are replacement ones for the indicators but they do affect flash rate. Not looked into what's needed for these yet.

Used these a few years ago and didn't rate them.

What happens if one of the LEDs fail? Does the whole unit fail or are they in connected in strings?

Does it work with IBS? I don't think it will because there wouldn't be enough room for the circuitry.

If it is all RED, then it won't illuminate your number plate correctly- so might be for off road use only and fail your MOT? Not sure on the law here.

There are a lot of other products out there. The choice is yours.

For the indicators you need a ballast resistor because the LEDs draw far less current than an incandesant bulb causing the flasher relay to operate incorrectly (all to do with discharge rates of charge held - LCR circuits) You will need one resistor rated at at least 25W per indicator bulb. You can calculate its value using Ohms Law.
