I am looking for a source for LED tape light rolls. I know this is an easy search on the internet, however they all say DC and I am looking for the type with the bridge rectifier so I can use AC.
Any leads for LED's is appreciated

I don't recall ever seeing those, though I'm sure someone has made them. However, why not just add a 5 cent diode?
What is your AC voltage source?
Even if you found a LED tape that had a bridge-rectifier I think it unlikely you have a fixed AC voltage that a bridge-rectifier alone would convert to a DC voltage suitable to drive an LED tape at ~12V DC.
Better to use a "standard" DC LED tape to take advantage of the huge volumes, wide selection, and pricing advantages rather than an obscure, limited selection, low-volume, undoubtedly higher-priced AC LED tape (if it even exists). Then figure out what you need to do to convert whatever AC voltage you have to a suitable DC voltage.
I order them from Amazon. Search for LED strip lights. They are 12v dc so if you are driving them using an AC transformer, use a bridge rectifier or diode to derive DC. The 120vac power adapters are inexpensive.

I get them from either eBay or Banggood, either place has 5 meter reels for less than $5.
For instance, on www.banggood.com, here's one.
And I bought a handful of fully adjustable dc regulators for a buck a piece, + free shipping -just to try them - they work great! I even splurged and bought a couple of dc regulators with LED voltage readouts ... for $1.59 each!
I brought three reels of these: https://www.ebay.com/itm/371728270731
Select the color you want, I used warm white, and the size, SMD model 3528, 300 LED's is 2.99 with free shipping. I use these in all my Flyer passenger cars and cabooses, the lighting is so much more even now, if you use the cool white ones it just looks like you have fluorescent lighting...Package should arrive in about 9 days...

Not bad Marty, I still like my source at $2.59 for the same reel of LED's.
Wow - that's cheap. Thought I was doing good at $5-6 a roll.
I also like using the 2596 DC-DC converters to get a fixed output voltage (plus I use a bridge on input, and a capacitor at each end of the 2596s to keep em lit), once you get to 11V, it's fixed brightness. I tried some of the smaller DC-DC units with no joy - but also running a 2 foot string of the LED's, so current might have been a little high.
appreciate all the feedback
