Above is the first light that I bought to go underneath the bottles. The reason I bought this light is because you can change the colour and it is rechargeable, unlike most others on the market.

However when it was delivered I realised it's much smaller than I expected, this meant the gin bottles can fit on it but it is not a comfortable fit. I also realised that it is meant for a car cup holder and the benefit of this is it turns on from the car vibration and only when it is dark enough. This means when the light is on a stationary platform it turns itself off. There is the possibility for me to try soldering the vibration and light sensitivity components out of the circuit, however, with the fit not being great for the bottles I decided it would be better to go with a different type of lighting. What this light did tell me was that having a light shining up through the bottle works well and should highlight the etching on the bottle.

These new lights are each a single colour and therefore I had to work out what colours are needed before buying them. They fit much better with the glass than the previous ones and the lights are very bright, shining through the glass well. The images show the light on its own; the light under the glass; and the light under the glass with liquid in it. The reflections of the light in the water make it have a good effect and I can see this looking good on the shelves in a bar.

I decided to buy red, orange, blue and purple as these correlate with the flavours. I bought a spare one to see how it works as I wasn't sure if they were single-use. I was pleased to discover they have an on/off switch so are not single-use. However, as they are battery powered I am unsure how long the batteries will last before needing to be changed.

The below photo shows what the lights look like. They are thin and will be hidden well by the bottles placed on top so you can only see the light and not the plastic parts.

The next stage will be to etch onto the glass to see how the light looks with the etching. It will also be important to see how it looks with liquid in the glass.
