Rolls-Royce Silver Dawn & Bentley MkVI Electrical Parts & Lighting

Exotic Car Parts stocks genuine and premium electrical parts and lighting for the Rolls-Royce Silver Dawn, Silver Wraith, Bentley MkVI and Bentley R Type — covering the 1946 to 1955 post-war Crewe-built range. We stock starter switches, starter motor components, voltage regulators, fog lights, headlamp bezels, a halogen headlamp upgrade kit, parking light assemblies, rear lamp assemblies and reverse light lenses. For any electrical part not shown, call us on +1 845 595 9822 seven days a week and we will source what you need.

Starter Motor & Electrical System Parts

We stock the complete range of starter motor components for the Silver Dawn, Silver Wraith and Bentley MkVI and R Type including the starter switch (UD4181) at $175, the starter motor driving shaft gear (DB986) at $487, and the starter Bendix drive shell (D54612) at $450. The 12-volt electrical system on these post-war cars uses a dynamo charging system rather than an alternator — we stock the correct 22-amp voltage regulator (RE10621) at $185 to maintain proper charging rates for the original lead-acid battery setup. Correct voltage regulation is critical on these cars — overcharging will damage period-correct electrical components that are difficult to replace.

Lighting — Fog Lamps, Headlamps & Halogen Upgrade

We stock the front center fog lamp assembly (RD5141) at $1,105, the fog light hinged flap (RD3256) at $155, the headlamp bezel (CD1717) at $250, the floor-mounted headlight dimmer switch (RD8143) at $135, the front parking light assembly (RD4587) at $195, the Bentley R-Type Continental rear lamp assembly in red (RD7066) at $460, and the clear reverse light lens (RD7890) at $210. For owners wanting improved nighttime visibility while retaining the period-correct appearance, we stock the Bentley MkVI and R Type halogen headlamp upgrade kit (RDHAL) at $240 — a drop-in replacement designed for the original headlamp housings.

What Electrical System Does the Rolls-Royce Silver Dawn Use?

The Rolls-Royce Silver Dawn (1949–1955) uses a 12-volt positive-earth electrical system with a dynamo rather than a modern alternator. This is an important distinction when sourcing electrical components — positive-earth wiring is the reverse of modern negative-earth systems, and incorrect parts will damage the system. The dynamo output is regulated by a separate voltage regulator unit, which is a common service
