I changed my brake booster because I was having a hissing sound and my brake pedal would sink slightly .

I didn't think changing booster would fix it, but I had tried almost everything else, and it's now fixed.

Then when I test drove it, I noticed my brake lights were stuck on.

I adjusted switch and all is good. Glad to hear you got your issue sorted.
