Quick refresher for those just joining the thread....
Project Halo started as a concept to integrate BMW Angel eye style DRLs into the 159/Brera/Spider triple headlight configuration. Initial development work was completed by myself & YonasH. YonasH pioneered the first sets of Halo's in a kit form that could be bought and installed as a DIY solution, however both of our efforts to disassemble the headlights resulted in failure or breakage and the only viable solution was to cut the lenses off, install the rings and glue the lenses back on.
As this was not a viable option, development ceased for around a year before starting up again after discussions with Coxy1 on headlight disassembly. Coxy1 was able to pioneer an approach the taking the headlights apart, but only if they were new ones where the glue had not yet had time to cure fully (several years of use on a car cures them fully!!)
Once this had been solved, I restarted development on the electronic controllers for the headlights to meet UK specifications and simplify the amount of electronics & wiring needed in comparison to the approach YonasH took.
Project Halo UK headlights are supplied as a set, with rings installed and working. All electronics and wiring for the DRL's is contained within the headlight and controller box (attached directly to the headlight underneath) The only additional wiring in the engine bay is power to the headlights from the PSU, which will be located somewhere near the battery, and switch wires attached to the engine fuse box (TBC).
This is what the headlights look like on the car:
And this is a description of there operation:
On start-up, they run Mode 1 once, then default to Mode 2 below:
Mode 1: Fade from 0% to 100% to 80% in sequence from Led 1 (inside) to Led 3 (outside)
Mode 2: Daytime operation – all Leds at 80%
Mode 3: Night operation – all Leds at 70%
Mode 4: Indicator Mode – Outer Led & inner Led rings at 70% - middle ring off
Mode 5: Main Beam - All rings at full power
Modes 3,4 & 5 are selected by +12v signal on each of the 3 inputs to the controllers. There is a 400ms delay after the indicator stops before the rings return to Mode 2,3 or 5. This is to allow the controllers to detect that the indicator has stopped flashing. I nay yet get that down to 250-300ms but any less and it doesn't work properly.
1) Will the headlights come with a warranty?
- We are looking into this, but as this project was only ever for ourselves, while we are happy to sell the units and cover our costs, we are not a commercial entity.
2) Will this be available in other countries
- We are focussed on the UK market for now, but once they are working well, we will consider supply to non UK markets.
3) Will this be available as a DIY kit to install in my existing headlights?
- Yes, but be warned, we have not successfully ever opened a headlight off a car without the use of a dremil to cut it open!
4) Will the units work with my factory fit Xenons?
- Technically, yes they will, but you would have to buy a DIY kit and set about your own £700 per headlight, headlights so I refer you to Q3 above!
5) Will these units work with after market HID kits, LEDs and other lighting mods?
- Yes they will. Both of the dev cars trialling the headlights have these mods and they work fine.
6) Will these units work with my automatic headlight feature?
- Yes, the switching between modes of operating is automatically controlled by the electronics inside the new headlights so it doesn't matter how they switch on and off.
7) How long will they last?
- The LED rings are quoted as having 20000 hours lifespan, but I can't vouch for that!! What I can say is we have done everything electrically viable to guarantee the LED's the most optimum / safe / stable conditions fully isolated and protected from the car's electronics system so they will last as long as they possibly could.
8) will they work with other vehicles?
- Technically the controller units can run 1, 2 or 3 rings each, so they could easily be adapted to be used in 147, 156, & GT's. We would just need to modify the code, and measure the headlights to get the right rings.
9) So how much?
- Price is TBC but around £450-500 for a full kit installed in two brand new headlights ready to fit for the 159/Brera/Spider. DIY kit price is TBC but obviously will be cheaper as it doest contain two brand new headlights!!
10) When can I buy them
- As much as Coxy and I would like to start letting you lot have them right now, its just too early to do so! A good man and technical advisor to the project always offers me the following sage advice.... Test, test, & test again! so you can have them when Coxy and I are 100% sure that they are bomb proof.
