Basilisk X Hyperspeed - DPI button doesnt shine like on images.

I have the same concern as well, based on the user manual, it supposes to have green led light when connecting via 2.4 GHz mode.

No it does not. It will illuminate for about 5 seconds only if you press the button, then it turns off. This is for both BT and the 2.4 GHz mode. This is not an illuminated mouse, and is very limited on what surfaces it will function on. Do not risk using this in the dark unless you want to accidentally step on it or place a dish of food or beverage on it without seeing it. This is likely how they are able to boast on their battery life which let's face it, if you wasted over 50 dollars, you can afford an extra damn battery now and then. Returning this thing, logitech MX anywhere will work on glass and at least has a small white light even though it's Razor who has the unhealthy fetish with their lighting features. Just remember to keep the stickers when you return it. Very disappointed.

And no, the Razor insignia on the palm area does NOT illuminate at all, whether you push the DPI button or not. It is an engraving, that you cannot see in the dark.
