100 uF tantalum SMD capacitor. Made by AVX. Unknown voltage; if that burned-out letter is a 'C', then it's 16 V.

If you measure the exact size (mm) I can narrow it down for you.
The length of this component is 6mm , the width is 4.3 mm and the height is 3 mm. I am amazed how fast the first comment appeared and thank you for the help .
I am sorry, I don't believe those measurements. 6 / 4.3 is a ratio of 1.4:1. The picture appears to be more like 2:1.
Just to be clear: "height" is the vertical dimension, from the PCB to the top of the component.
Please double-check.
Could it be 7.30 x 4.30, 3.10 mm high?
If so, it's [one of these](https://www.digikey.com/products/en/capacitors/tantalum-capacitors/59?FV=-1%7C478%2C7%7C17%2C7%7C2%2C7%7C3%2C46%7C17482%2C69%7C409393%2Cmu100%C2%B5F%7C2049%2C-8%7C59%2C1500%7C10308%2C1500%7C10653%2Cmu16V%7C2079&quantity=0&ColumnSort=1000011&page=1&stock=1&pageSize=25). Any one of them should work.
I made some [Pictures](https://drive.google.com/drive/folders/1fKtCwL5o59HjbUZH7yjWRo-FzaDh7fJq?usp=sharing) with the measurements to be 100% sure.
And thx for help .
How does a capacitor even fail that catastrophically on a god damn bike light? This makes me sleep uneasy at night knowing how many power supplies I have plugged in to the wall with similar branded and untrustworthy components. Miss my linear bulky PSUs I could trust ugh. Maybe I am just old.
If left outside during the day then it could get pretty toasty even when turned off. They also likely cut corners in the derating department. There might also be voltage spikes on the line.
China has a problem with corner-cutting at all steps in the production chain and it's not just on jobs for foreign customers. So we can't even blame the manufacturer. They might've been supplied dodgy components which they then used in good faith.
Hi sorry for a late reply. To get it out you need to desolder the red and black wire and unscrew it from the housing the silver part ( front of the body of the light) is held with 2 pins so it is impossible to get it out without a soldering iron.

Sorry my bad The length of this component is 7.2mm , the width is 4.4 mm and the height is 2.8mm. Now I did use a caliper.

Well done!

How did you get it out of the casing? 🤔

frame them and wear them like glasses 😂
