Royal Enfield RAC00390 – Electronic Flasher Relay Unit for LED Indicators on Himalayan 450 & Guerrilla 450 – Genuine OEM Indicator Relay

Royal Enfield part RAC00390 (and its suffix variants RAC00390/C, RAC00390/E) is the genuine electronic flasher unit / flasher relay used to control the indicator blinking on the new 450 platform bikes. Bike-Parts-RoyalEnfield lists RAC00390/C – Flasher unit as a certified Royal Enfield genuine part “exactly the same as the one mounted at the factory when the vehicle was new.”

RAC00390 – FLASHER RELAY UNIT, for LED Indicators, and their Himalayan 450 parts book pages (Gold Dip, Playa Black, Brava Blue, Yellow Ribbon colourways) show product code RAC00390, normal qty required: 1, confirming it as the stock flasher relay on the Himalayan 450.

Multiple aftermarket listings further confirm it as the OE reference for Himalayan 450 and Guerrilla 450 – for example, an “Electronic Flasher Compatible With Royal Enfield Himalayan 450 Guerrilla 450” explicitly quotes OE/OEM part number RAC00390/C. Export data also lists “INTERMITTENT UNIT, ROYAL ENFIELD, HIMALAYAN – flasher unit, part no. RAC00390”, matching the same electronic flasher role.

This module is designed for LED indicators and correct flash rate on the 450 platform. If your indicators are not blinking, blinking too fast, or stuck on, a failed flasher relay is a common cause. Replacing it with the correct RAC00390 restores factory timing and reliability, and avoids jugaad resistors that can overload the wiring.

🔴 We only claim confirmed, multi-source fitment: Himalayan 450 & Guerrilla 450. Not advertised for J-Series, older Himalayan 411 or other models (see table).

Key Features

• Aftermarket cross-references confirm OE/OEM RAC00390/C for Himalayan 450 and Guerrilla 450.

• Designed to drive LED indicators with the correct flash rate – avoids hyper-flashing and error behaviour.

• Plug-and-play with the original wiring harness on 450-platform bikes (no cutting or extra resistors when indicators are OE).

• Solid-state electronic design for stable operation, long life and consistent timing compared to generic 2-pin mechanical flashers.

• Ideal as a direct replacement for failed flasher units or when converting back from jugaad/universal relays to OEM-spec.

Compatibility Table

These two share the same 450 electrical architecture, so RAC00390 is treated as the OE flasher relay for both.

However, connector styles and mounting vary between models. To avoid returns, we do NOT advertise plug-and-play fitment on:

• Himalayan 411 / older Himalayan BS3/BS4

• All J-Series (Classic 350 Reborn, new Bullet 350, Hunter, Meteor)

• 650 Twins (Interceptor, Continental GT, Super Meteor, Shotgun, Bear)

• Any UCE-era Classic, Bullet, Thunderbird, Electra

On these, treat it strictly as a universal electronic LED flasher, only if your electrician is ready to adapt connectors and verify load.

Variants

Different catalogues show suffix revisions:

• RAC00390 – Base number used in Himalayan 450 parts book pages (qty 1).

• RAC00390/C – Listed by Bike-Parts-RoyalEnfield as “Flasher unit”, and by OEM/aftermarket sellers as genuine flasher unit for RE.

• RAC00390/E – Appears in export / HSN descriptions as “Flasher unit Part No. RAC00390/E” for Royal Enfield, confirming another running revision.

On underthehood.co.in, you can keep one combined product and specify:

“Supplied as RAC00390 / RAC00390/C or later equivalent (E, etc.) depending on latest OEM revision – all are genuine flasher units for the 450 platform with identical function.”

FAQs

Q1. What exactly is Royal Enfield part RAC00390?
It’s the electronic flasher unit / indicator relay that controls the blinking of the turn indicators on the new Royal Enfield 450 platform. Bike-Parts-RE describes RAC00390/C as a genuine “Flasher unit”, and Hitchcocks labels RAC00390 as a flasher relay unit for LED indicators.

Q2. Which bikes are confirmed to use RAC00390 from the factory?
Hitchcocks’ Himalayan 450 parts book pages show RAC00390 as the flasher relay (qty 1), and aftermarket OEM-cross listings quote RAC00390/C as the OE/OEM reference for Himalayan 450 and Guerrilla 450.

Q3. Is RAC00390 compatible with LED indicators?
Yes. The Hitchcock’s accessory description is “FLASHER RELAY UNIT, for LED Indicators” under product code RAC00390, and aftermarket electronic flasher listings built to this number are specifically targeted at LED-equipped Himalayan 450 / Guerrilla 450.

Q4. Can I use this on older Himalayan 411 or J-Series Classic / Hunter / Meteor?
There is no clear microfiche or dealer evidence that RAC00390 is the OE flasher for those bikes. Electrically, it may be adaptable as a 2-pin LED relay, but connector and mounting differences mean we do not guarantee plug-and-play fitment. Treat it purely as a custom retrofit if your electrician is comfortable with rewiring.

Q5. What are the differences between RAC00390, RAC00390/C and RAC00390/E?
They are simply revision codes of the same basic flasher unit – export data and EU catalogues show RAC00390/E flasher unit, while UK and India listings commonly use RAC00390 or RAC00390/C. Functionally, they all refer to the electronic LED flasher relay for Royal Enfield, especially the 450 platform.
