So Its been a while, work has got in the way, and I am waiting on a few supplies to arrive.
This week I finally tackled retro fitting the LED bulbs into my Marchal spots. I thought that this would be a shocker, but by luck I helped myself out and bought out of a choice of two bulbs in the brand I settled on, the right H3 led bulbs that easily fit my spots. I decided I had to drill a hole in the buckets of the spots to allow the light bulb to fit.. Even though the LED's are H3, they are 28mm longer in length. The actual bulb length is the same, so there is no issue there with sitting it in the holder, but the spot bucket wouldn't go on over the extended length. I pulled the bulbs apart and took off the heatsinks, when I bought the bulbs I dint know you could do this, so this was a stroke of luck. This allowed the original spring clips to hold the bulb in place as per the original one, with a bit of wiggling to get the spring clip down each side of the bulb. I drilled centre holes in the bucket of 20mm ID, so the back of the bulb and the wiring could pass through, and then I used the heat sink assembly and spacer to tighten down onto the back face of the bucket, so the bulb is now anchored at by two points. By having the bulb fastened to the bucket, the bucket now acts as the heatsink for the bulb, albeit with a large surface area. The back of the bulb is sealed with a rubber bung, which I have added some sealer to, so there is no chance of water getting in the bulb circuit. I printed off some silent block rubber in TPU95, with an infill of 30%, to add to help with vibrations you can see one in the last photo on the threaded section of the mounting bolt. Where the spots attach to the aluminium mounting plate, which in turn is silent blocked onto the fairing. I think the out come looks pretty good, and not too out of place with the wires exiting the back in the centre.
The bulbs supposedly have a high and low beam function
Heres a bit of a blurb on them
Producing high-performance pure white lighting thanks to the Premium LED chips and the chrome reflectors that compose them, the adjustable H3 LED bulbs for low beam, high beam and fog light will be able to adapt to the most limited in space headlight optics. Their 360? directional heat sinks are composed of aluminum slats that can be easily "modeled", they will find their seats by adjusting perfectly to the constraints of each optics.
The H3 adjustable LED bulbs are anti OBC error, the connection is "plug and play", so there is no change to provide, you simply replace your original halogen bulbs with adjustable H3 LED bulbs.
Characteristics:
- 8000 Lumens for a pair of H3 LED bulbs
- 6 leds PREMIUM per H3 bulb
- Lighting Color: Pure White 5500K
- Materials: Aviation aluminum
- Intensity: 12V and 24V
- Operating temperature: - 40? C to 300? C
- CE Standards
