I've been looking for one for a long time with no luck "900 STRA" one, he had different ones didnt he?
Transformers Bumble Bee Cal. Replica license plate | eBay Maybe they can customize one for you. Good luck.
Bumblebee had several license plates. Beater Camaro had "489 PCE" in robot and vehicle mode. 2007 Concept Camaro, ROTF Camaro and DOTM Camaro had "900 STRA" in vehicle mode. DOTM Bumblebee also finally had that in robot mode. The Hasbro toys for DOTM followed suit. Here's where the problem begins: 2007 Bumblebee and ROTF Bumblebee had "4NZZ454" in robot mode. Most Hasbro toys for 2007 and ROTF used that as well (including Classic Camaro Deluxe Bumblebee). 2007 Deluxe Bumblebee (including the Premium version), ROTF Bumblebee and Human Alliance Bumblebee had "4NZZZ454", with an extra "Z", presumably an error. Other license plates: The life-sized robot prop had "5LKZ213" on the Hoover Dam set for the 2007 movie. When the prop went on tour, it had even more plates: "BUMBLBE" on several 2007 venues, "FXPERTS" in 2008 and "KDM 0814" since 2009. The ROTF and DOTM video games use the license plate "5BBM2" (mirrored on the right side) in robot mode. EDIT: That plate from the eBay auction is not Bumblebee's. It's Ironhide's. http://tfwiki.net/wiki/Image:MovieIronhidevsLost.jpg
900 STRA I dont think ment anything it was used in both ROTF And DOTM (Black and Grey in colour). However DOTM it had two validation stickers one in each corner .
The original ROTF plate was auctioned off two years ago. Hero Bumblebee license plate from Transformers: Revenge of the Fallen
