Amazon has the WUBEN E2 Pulse at $12.99 tonight, down from $16.99 on the same listing. WUBEN’s own store runs $19.97 against a $29.99 list price, so Amazon holds the sharper end of the discount by seven dollars. Both storefronts showed stock during tonight’s check.

Price is only part of the draw. Weighing 10.7 grams with its battery installed, this keychain light matches a pair of wireless earbuds on the scale, and it measures just 41.4mm long. Hardware that light stops being gear you remember to bring. It simply lives on the ring.

Three lights in a 41.4mm body

Forward output peaks at 150 lumens, and medium and low settings run 50 lumens and 5 lumens for close work. Beam reach is 26 meters, sized for doorways, tents, fuse boxes, and the last unlit stretch of sidewalk. Output on high steps down after the first minute, a standard trade in a body this small.

One long press cycles through the light groups, moving from the main beam to the side light and then the signal modes. A single round button runs everything, and a gloved hand can work it without looking down. Controls stay simple because the light stays small, and a buried menu would defeat the point.

Side white light adds 80 lumens on high and 10 lumens on low, aimed at reading, desk work, and digging through a bag. Built into that side light is a heartbeat mode, a slow breathing glow that pulses through the translucent shell. Paired with a glow-in-the-dark body, the pulse makes the light easy to find on a nightstand or at the bottom of a pack.

Signal modes round out the set, and they push this past novelty territory. A red beacon marks a position, a red and blue flash covers roadside warnings, and the breathing glow doubles as a visibility light on a collar or zipper pull. Drivers read a small pulsing light long before they read a reflective tag.

Built to live on a key ring

A magnetic tail sticks the light to a hood, a breaker panel, or a fridge door, which frees both hands for the actual job. Ceiling work, engine bays, and dark closets all play better hands-free. Snap it on, aim the side light, and get to work.

Construction mixes an aluminum alloy frame with a polycarbonate shell, sealed to IP66 against water jets and dust. Drop protection is rated at 1.5 meters, which covers the falls a keychain light actually takes. Rain on a night walk is a non-issue, and a drop onto concrete is survivable.

WUBEN backs the light with a five-year warranty and a 30-day return window, coverage that outlasts most gear at this price. Registration adds repair support for build faults, which is real backing for a light that costs less than lunch.

Power comes from a built-in 120mAh lithium polymer cell that charges over USB-C, the same cable most phones already use. Runtime runs seven hours on low, one hour on medium, and about thirty minutes of stepped-down output on high. A charging cable and a key ring ship in the box.

Carry options run past the key ring, since the package includes a quick-release buckle and a chain. Worn as a necklace, clipped as a bag charm, or hung from a zipper, the light stays reachable without a pocket check. Two colorways carry the deal, Gradient Black and Gradient Red, and both glow after the lights go out.

Buyers have found the size claims hold up, with the listing sitting at 4.3 stars across 1,179 ratings in tonight’s check. Feedback on the maker’s page runs 4.95 across 21 reviews, smaller numbers but the same direction. Small lights live or die on whether people keep carrying them, and a 10.7-gram light has the easiest case to make.

What the discount changes

Our September write-up covered this light at $16.99 on Amazon, so tonight’s price undercuts our own coverage by four dollars. WUBEN direct at $19.97 still beats its $29.99 list, though Amazon wins the comparison that counts tonight. Deal pricing at this level tends to move without warning, and no end date is posted on either listing.

Pick one up if your keys carry no light at all, or if a phone flashlight keeps losing to occupied hands and a dying battery. Dog walkers and night commuters get the clearest win here, since the signal modes were built for exactly that job. At this price, a second one for the glove box is an easy call.

Skip it if you need real throw, because 26 meters runs out fast on open ground. Skip it, too, if long runtimes on high output are the priority, since physics wins that fight at 120mAh. Shoppers who want a flatter pocket light with more output can step up to WUBEN’s own G5 at $19.99, though it gives up the keychain size that makes this one work.

At $12.99, the Pulse is priced like a spare and carries like one too. Right up until it lights the lock.
