Which bike light, aren't that to be seen kind enought? I just bought a giant escape 2 and have been using it to go to work. When is time to come back home is already dark and I'm planning to get a light. Asked about one in nearby bike shop and they suggested me the following (https://www.qoo10.sg/item/GENUINE-GIANT-ZOOM-LIGHT-BICYCLE-LIGHT-HEADLIGHT-LIGHT-TORCH/531628737):

Comparing it to the models from Giant website https://www.giant-bicycles.com/us/lights it seems to be on the cheap side.
I also noticed they classify lights as &quot;to be seen&quot; (cheap, i.e. hl100, hl200) and &quot;to see&quot; (expensive, i.e. hl500).
So which one would you advise me to get? If hl100 is not enough perhaps hl200 is ok, or I better go with the hl500? In principle my intent is to use the light to see.
So you're riding at night - are the routes lit by streetlights?  Or are you riding in pitch darkness?
The former would recommend two &quot;be seen&quot; lights for the front and two for the rear, and the latter would require at least one Seeing light and a backup for the front and still two on the rear.
I'd strongly recommend adding some combination of spoke reflectors, reflective sidewalls, and reflective clothing to go along with your active lighting.   DOT tape is available in appropriate colours and costs nothing to operate.
Be aware you do not need a Giant-brand of light on your Giant branded bike.  The only time such a thing is needed is if there are built in connectors to an internal wiring harness or similar.  Otherwise you're free to fit whatever lights you like.
I personally run two completely different front lights plus a head lamp.  The main one has an &quot;hours remaining&quot; readout which tells me if I can make it home before it goes flat.  Likewise I have several rear lights each with their own power, so they're less likely to all go out at once.
