If you are on an extreme budget it's a good option for a bright tail light. There is also a seller on Amazon offering them for just a touch more, shipping from a US warehouse.
Headlight is going to be more difficult. Lots of good "be seen" lights in that price range, but more powerful ones that work well will be a tougher find.
I have a few of the Superflash clones. I remember reading someone's circuit analysis of a real Superflash and one of the DX versions, and there were differences. Nothing I can remember, and nothing substantial, but differences.
They are great lights for a great price. Get a few.
DX has a lot of lights that put out a lot of lumens for very little money. If you can manage the detached battery pack, you can get a massively bright light for under $40. I have
this one, it's bright, it can induce seizures at 50 feet and it has more than enough battery life for my needs (it lasts three 1.5 hour long commutes, usually on low,before I get paranoid and charge it, even if it isn't low.)
