On the other hand, if you only have a dim rear blinker, the driver will only be able to spot you when they are quite near. This gives them very little time to properly change lane when overtaking, making it more likely that they will pass close to your bike.
With that in mind, I decided to add on a rear light for my Avanti Inc 3. Although the current NiteRider Solas 2 Watt rear light is very good, an additional light will complement the Solas and make my bike even more visible.
Another reason is that using both at the same time will practically eliminate the chance that my bike has no rear light if one of the lights suddenly spoils. There is such a possibility as my Avanti is a wet weather bike, and riding in the rain may cause the lights to spoil (even though they are advertised as rain resistant).
I am a fan of the Moon Comet series of lights, mainly because these lights use COB LEDs, which gives off a really nice organic glow which I like. They are also small, lightweight, and have a decent battery life. The rubber strap mounting provided is really versatile and easy to use, with quite a bit of room for adjustments. For more details on COB LEDs and the Moon Comet Front Light which I have on my Dahon Boardwalk, just check out this link!
Moon Comet Rear Light. 35 lumens compared to 100 lumens for the front light.

Viewing angle and the range of the light
The rear light comes with an additional saddle rail mount, which the front does not have
Looks exactly like the front light, except that the LED is red in colour. For more details on the light, check out the Moon Comet Front Light review.
What's inside the box: The various mounting options that come with the rear light
Saddle rail mount. Useful if you are not using a saddle bag, and don't have enough seatpost length to attach the light onto the seatpost.
Even though I did not attach a saddle bag onto the saddle of my Avanti, I am still unable to use the saddle rail mount for the rear light, as the rear-rack-mounted-saddle-bag gets in the way. The picture below shows what I mean.
No way to use the saddle rail mount or the rubber strap mount on the seat post as the saddle bag on the rear rack will block the rear light
To overcome this issue, I decided to mount the rear light onto the tail end of the rear rack instead. That was my original intention for the NiteRider Solas 2 Watt rear light, but unfortunately I was unable to engineer an elegant and unobtrusive solution for that.
With this new Moon Comet Rear Light, it has different mounts, and after some experimentation, I was able to fix up something that looks simple and works well. Check out the pictures below!
Light clip (shown on bottom left) is taken from the saddle rail mount. That is the part that I need to fix the rear light to whatever DIY jig that I have.
I used an L-shaped stainless steel plate as my DIY mounting. It was sprayed black to match the colour of the bike. Mounted onto the rear rack with some standard bolts, nuts and washers. Nylon locknuts were used to prevent self-loosening.
When mounted, the Moon Comet rear light is positioned exactly in the middle! Just what I wanted.
The Moon Comet rear light nestles nicely on the rear rack, protected by the saddle bag and the rack itself. This prevents me from kicking the light accidentally when I swing my leg over the rear of the bike.
On/Off/Mode button is easily accessible on the top, and the light can be removed easily for charging. This is what I mean by a simple and elegant solution! It is also very secure and does not droop down on bumpy roads.
