Product Description

With a main one watt LED and two smaller side facing LEDs the Mars 4.0 is one of the best sealed rear lights. A tool-free removable rear plate covers the batteries, but beyond the battery plate everything is sealed. The power button is part of the secondary seal behind the internal battery tray. A lifetime warranty and excellent performance are matched by a run time of over 150 hours, and there’s an array of top quality tool-free mounting options.

Strengths:    Bright! Probably too bright for group rides. Definitely makes me visible on late night commutes.

Bottom Line:   
MSRP is $25 and it's a great rear light for that price. I feel a lot safer knowing how bright it is behind me.

Strengths:    Bright light at night, great mount - very flexible (I have it mounted on the seat stay), can change the angle, easy to use quick release.


Weaknesses:    The only thing that really bothers me with this light is the on/off switch. At night, when I get home from my nightly commute from work, it is difficult to find the on/off switch. It takes me about30 seconds to turn off the light because looking at the bright light at such a close distance, you can't see the little on/off switch and is difficult to find the exact proper spot by feel to turn it off. Wish it had a strobe pattern, not just a blinking flash.

Bottom Line:   
Overall, I like this light. Wish the light was even brighter, however, during daylight. I want cars to notice me, not just see me, when I am on the road during the day. During daylight, you can see this light blinking, but it doesn't glare at you. I guess you have to spend $300 for that feature. Overall, I reccomend this light. This is a good, inexpensive light. I'm only giving it an overall rating of 4 Flamin' Chilis because of the on/off switch being so difficult to turn off at night.

Date Reviewed: January 23, 2011

Strengths:    At the moment not many can out shine this 1 watt light for the price! Had several bikers ride up and ask me what brand and model it is. Works in heavy rain and battery life is good.

Weaknesses:    Side markers could be brighter. Only two flash modes. Steady and Flash

Bottom Line:   
Great light and price for a 1 watt led tail light. What can make this product better is brighter side markers and different Strobe patterns.

Strengths:    Just wanted to throw down a review for this great product! never before have i felt so safe while hearing a car coming from behind me! the only way they won't see me is if they're seriously messed-up...in which case you're scuppered, anyway! super-bright, attention-getting, and looks good in the day when it's not lit-up.

Weaknesses:    none yet. i make sure the main led is pointed right in the driver's eyes as they come up behind me. lol.

Bottom Line:   
great, confidence-inspiring product! can't put a price on safety!
