I just got pulled over tonight too. (Renton WA)
I have a brake light out on the side, which is a writable ticket, and my top light was out too!

But I noticed when he got behind me and he followed for quite a ways. I didn't feel I was speeding, but when I was finally about 50 feet from my house, he finally turned on his lights.
He said he paced me at 10+ at different areas. (Followed me for about 2 miles.) It probably was true, my little RAV4 has slightly larger tires, which causes my speedo to register low, and I was driving at the limit or 5+ mph higher, so he was right...
So he checked my record out, (it's super clean) told me to fix the lights and SLOW DOWN! I also didn't have my insurance card with me for some odd reason, but he let that go too. (That's a $500+ fine!!)
Got off with a Warning! Wheew!
