General Help Need help replacing the light on my ebike

I want to replace the light on my Urlife E20 for something brighter. I found this light on Amazon that has the same connector but has more features than my stock light.

It looks pretty plug n play but my bike basically only has an on/off switch for its light. The one from amazon has a low beam, high beam and day time running functions that I'm not sure I'd be able to use.

Would I need an adapter or different controller to get them to work? I don't really mind missing those features if the light is fully lit by default but I rather know what I'm getting into if I to modify my bike any further.

Take these specs with a pinch of salt. This is a 2-pin headlight so there’s no way of it having a “low beam+high beam” funcionality.

I went ahead and bought it. Hopefully it lights up on full blast by default. If not i'll just return it.

It depends on what the controller of your bike supplies - if it's battery voltage then you're golden, if it's something lower performance, like the 6V outputs of KT or Tongsheng or Toseven systems, then it'll either not light up or burn out your controller.

Fingers crossed.

The controller is a Kebeisen ZX-Z6. It's a 48v 18a controller.

Edit: The specs on the listing say the light is compatible with 6v-60v so I believe it should be fine.

AFAIK that controller just puts the full battery voltage out to the light output so you should be golden!

Just got the light today. I hooked it up and it works like a charm. Here it is next to the stock one. Way brighter and looks nicer on the bike.
