Hello cynthia cross , thank you for posting on our Forum!  Probably the best place to start is to read this blog post from way back in 2014:

https://www.brickstuff.com/blog/what-lights-do-i-need-for

That article talks about several of the main options-- long story short, we always recommend people begin with one or two of our Starter Kits.

Have a look at that article and let us know if you have any additional questions.

Thank you!
