The most effective option on our list is the LEDs that take up to 32.9 watts, thereby winning the crown in terms of energy efficiency. Halogens are followed by HIDs that consume around 49.1 watts, making it the second least efficient bulb in the headlight hall of fame. Halogens are the least energy-efficient bulbs that take up to 56.7 watts. When choosing our automotive accessories, we should always strive for the most energy-efficient options. However, HIDs are strictly for projectors because they are too bright for reflector headlights, ultimately blinding the drivers.Īn energy-efficient bulb converts all electricity to light energy without producing any heat at all. Meanwhile, LEDs are an ideal choice for reflectors and sometimes for projectors as well. Therefore, when it comes to halogens, they can be used for both projector and reflector housings. However, most vehicles feature halogens and their reflective housings as the standard headlight. I’ve heard very good reports about LUX LEDs but LEDs can never be as bright as HID at this time.No type fits all of the headlights. The hard part with an M3 is the design of the lights is an inner fitting that takes the lamp and a conductive optical light path to the outer rings which is why the outer rings are often dimmer than the inner rings. In my case I really prefer HID because of the brightness. They are so bright the inner rings tend to flare a bit at close range. External wiring needs to be routed under the snap on headlamp cap. Installation is more work and requires an external connection to the battery to power the external ballasts. They look really good and pass the acid test, that is when you pull up behind another car in full daylight even if it’s dirty you can see clearly the inner and outer rings. A 6000K (Nice crisp pure white) HID 35 watt lamp outputs about 2.5 times more than the 35 watt stock halogen lamp. There is a YouTube install video for this which is very helpful except I totally disagree with not bothering to disconnect the battery or handling the HID bulbs with anything other than gloves. Apart from that the kit was well presented and represented much better value for money than the LED kit at around $100.00 cheaper with many more parts. The seller from Alpine MSS was co-operative on this and assured in future these would be soldered. It turned out this was wire wrapped and not soldered on my install and another one I did. There is a “dummy load resistor” on these to stop lamp fail errors. Wiring also has to be tucked under the Snap-On headlight cover cap. HID Version: More work fitting and require fitting of an external relay plus two ballasts. It’s hard to get a good light output on the M3 due to the design of the headlights unlike other cars like Audi that have front facing individual LEDs Look great around dusk but have fairly low output as a true daylight running light. Not very bright, not much more than stock if that. They also draw very little power compared to the regular 35 watt H8 lamp and are around the same brightness. At 10 watts they run fairly cool and an LED has a very long life expectancy. Relatively easy to fit, are completely enclosed in the headlamp enclosure and require no external connection to the battery supply. The manufacturer was very keen to co-operate and committed to improving. There was no in- line fusing on these which is a real worry if they fail short. The wire quality was not what you expect hook up wire rather than silicone coated high temperature wire. The controller module failed on over temperature constantly and the wiring had to be extended enough to be able to place this at the bottom of the headlamp housing where it was much cooler. I did not like the wire harness that came with this model and had to completely rework it. They plug straight in to the factory connector which goes to a small controller, then to the LED H8 assembly. This was a 10 watt LED mounted rear facing on an aluminium block and a bolt on heatsink. Very easy to fit, although the AngeliBright was a bit of a pain with the heatsinks. There are pros and cons for both, so I’ll list what I found and would be very interested to hear of others with experiences of either. As I’ve mentioned before my background is Electronic Engineering so this was a fairly easy install for me. I’ve had both now and am running the HID’s I got from Alpine MSS, USA also had a set of AngeliBright version 3 -10 watt LEDs. Hi Everyone, thought this topic may be of interest as Angel eyes seem to be quite a common add on and quite easy to do.
