Royal Enfield 1120045/A Trafficator (Indicator) Assy with Bulb – FRH/RLH | Thunderbird X 350 ABS (BSIV/BS4) & Thunderbird X 500 (BS4)

Confirmed for Thunderbird X only (see compatibility table). Do not assume fitment for Classic/Bullet/Standard, Thunderbird (non-X), J-Series, Himalayan/Scram, or 650 Twins unless your parts catalogue maps to 1120045.

Product Description 

If your Thunderbird X indicator is broken, loose, water-filled, dim, or not blinking consistently, replacing only the lens or using a universal indicator usually creates wiring cuts, poor mounting, and repeat failures. Royal Enfield 1120045/A is the genuine Trafficator (Indicator) Assembly with Bulb specified as FRH/RLH (Front Right / Rear Left)—the correct OEM-style unit designed to restore factory fitment, bulb seating, and proper mounting stability.

Royal Enfield microfiche/dealer catalogues list this exact part number as “TRAFFICATOR ASSY WITH BULB FRH/RLH”, confirming the position mapping and part identity. 
Fitment is verified by multiple sellers for Thunderbird X 350 ABS (BSIV/BS4) and Thunderbird X 500 (BS4), making it the correct replacement for those variants when you need a direct, spec-correct indicator assembly. 

Best practice: order the right quantity based on which corner needs replacement (FRH/RLH are the same unit), and confirm your current indicator position before purchase to avoid wrong-side ordering.
