Yes, I reckon the wires are about 16 AWG and the current draw is said to be about 3.15A for the landing light part of the new AveoMaxx 6-in-1. I would return it for repair under warranty, but Aveo voided that because I removed three screws holding the front lens in place. I was trying to look for an obvious fault and also see how the 'beam angle adjustment' works, but there is none. After exiting the body, the wires are soldered to the control circuit board, which is embedded in epoxy. I'll put some thought into how to heat the board as Chris suggested and give it a go. Mouser Electronics sell the LEDS for about $50 each if I screw it up.

The LED OEM (Luminus) data sheet says that the used and spare cathode (just visible at the top of the LED base) are interconnected, but there would be more strain on the main wire to reach the spare solder tab. Perhaps a small jumper between the first and second cathode (and same for the anodes) would be smart too, but I need to re-attach the wire without damaging the LED. I have some ideas about how to provide strain relief and protection for the wires Bob, but what do you think is the best way to prepare and re-solder to this tiny solder tab, which is only about 1/16 x 1/8" in size? For reference, the screws are M3. What AWG are these wires? How much current does the LED draw? The first idea that comes to mind is replacing the wires with smaller gage still sufficient to the current. I'd bet you can go down to 24 or perhaps 26AWG. Remove all the existing 'fat' wires and bring smaller leads to the outside of the enclosure. Use some form of adhesive/sealant to secure the wires as they pass through the housing. Once in the more robust, outside world, figure out some form of connector . . . or perhaps splice to more robust leads and secure the joint mechanically under a band-clamp. You need a soldering iron with a small tip and some 63/37 solder. I'd clean off the pads with a piece of solder-wick, re-tin the pads with small dots of solder. Tin the ends of wires to be attached. Then 'tack' the wires onto the pads. Bob . . . ________________________________ Message 2 _____________________________________ Time: 07:39:10 AM PST US From: "Robert L.

Okay, you can drop the wire to 22AWG and make the job MUCH easier.

Okay, you've not bounded your risks. $50 + time to do the experiment is not the upper limit . . . if you 'screw it up' it may be because you don't have the tools and techniques which the factory does have. An out-of-warranty repair might be cheaper than a new LED assy and the risks for lack of tools and process go to zero. I'd sure talk to the factory first . . . and ask them, "why 16AWG lead wires?" in a 5A or less circuit.

On the face of it this would seem simpler?

For example one made by Planepower. On the >face of it this would seem simpler? It is. The legacy components approach pre-dates all-in-one by 70 years or so. The B&C LR-series regulators include active notification of LOW VOLTAGE which is generally not included in the all-in-one products and should be part of your planning.
