Leveling kit and new LED headlights

Good morning everyone!

So I have 2 questions here. I am wanting to put a leveling kit on my 07 tundra, and replace the factory headlights with LED headlights (just the bulbs).

So I am on a VERY tight budget and can’t put much into either of these, so I am looking for input on what is going to get me the best quality for the cost.

I am planning on installing the leveling kit on my own as I definitely wouldn’t be able to afford to have someone else do it

Also I wouldn’t mind some advice on what size of leveling kit to put on.

Thanks!
