You all have been patient so here's an update for you. The biggest milestone is that the electronics design has been finalized baring any unforeseen conditions from testing. The first electronics boards are being manufactured and tested now.
The prototype housing and lenses have been test fit and some minor adjustments have been made. We wanted the lights to be totally plug and play so it was good to confirm the stock Z bulb connectors fit snugly.
Also the design for the diffusion plastic has been test fit and looks good. We may end up manufacturing this piece in house in order to keep the final price down as much as possible.
One of the most frequent questions we get is how much will the tails be. Unfortunately we really can't say yet. We are in active talks with an injection molder and that is the biggest unknown at this point. Once that is nailed down, we can probably give a pretty good estimate so you can expect that update as soon as we have finalized negotiations.
