I'm hoping to get some help finding a replacement lense for this light/siren. It's mounted on our vintage chiefs vehicle we use for parades and such. I didn't want to climb onto the vehicle, so I got the best shot of the ID plate that I could. What I can make out reads "Champion Siren" and a listing for Darley. Any help is appreciated. If needed, next time I'm at the fire hall I will get a ladder and try to get some detailed shots of the label or at least try and see if the model and stuff can be made out. Thanks!
