Royal Enfield 1010066/C – Warning Indicator (Dash/Speedometer Warning Lamp) for Classic 500 Euro 4 & 350 BS6 UCE | Genuine OEM

Royal Enfield 1010066/C is a genuine OEM WARNING INDICATOR unit used in the instrument / warning-lamp circuit on specific UCE 500 Euro-4 models. In the official parts diagrams, this part appears under SPEEDOMETER assemblies for multiple Classic 500 Euro 4 variants and under HEADLIGHT ASSEMBLY for Bullet Trials 500 Euro 4—making it the correct replacement when the original warning indicator stops illuminating, flickers intermittently, or fails after water ingress/age. 

This is the “small but critical” electrical part that helps you see important warnings on your console. Replacing it with OEM avoids common issues seen with generic indicator units (wrong connector fit, poor sealing, inconsistent brightness). 

Supersession / ordering note: older catalog number 1010066/A (Warning Indicator Assembly – ABS) is shown as replaced by 1010066/C, so 1010066/C is typically the correct current supply when your microfiche points to 1010066/A.
