About This File
GTA 4 (not tested in GTA 5) - This is the London Fire Brigade (LFB) Fire Rescue Unit (FRU) siren modification for GTA 4. This siren is commonly heard on the older London Fire Brigade (LFB) FRU Atego's. This siren sounds EXACTLY what it's like in real life, and has the AMAZING hi-lo! ;) A great quality siren!
