# Butler Chrome License Plate Light for Early E-Type Series 1

Vehicle Overview

This guide covers sourcing an original or reproduction Butler chrome license plate light for early Jaguar E-Type Series 1 3.8 models, specifically the earliest flat floor/welded louvre bonnet variants from the 1961-1964 production window.

Understanding Your Requirements

Before sourcing, determine:

  • Production year and month — Butler lights were fitted only to the earliest Series 1 3.8 cars before Lucas took over electrical component production
  • Fitment scope — whether you need the rear license plate light only, or the matching front sidelights as well
  • Restoration standard — concours-level authenticity (where Butler branding and casting marks matter) versus driver-quality rebuild

Sourcing Recommendations

Primary Suppliers

XKs Unlimited — carspanner.com/go/xks-unlimited

  • Gold standard for Series 1 early authenticity in the US market
  • Stock E-Type lighting with reproduction availability that varies by specific unit
  • Recommended approach: Call directly rather than browsing online. Ask specifically for Butler-marked stock, not Lucas equivalents. They work with early flat floor cars regularly and can advise immediately on availability or point toward NOS examples still in circulation.

Classic Jaguar — carspanner.com/go/classic-jaguar

  • Stock E-Type lighting but focus primarily on later Series cars
  • Secondary option if XKs Unlimited cannot fulfill your needs

Secondary Market

eBay Motors — Use with caution only

  • Verify seller photos show actual Butler script or casting mark before purchase
  • Misidentified Lucas units are frequently sold as Butler units

Important Fitment and Sourcing Notes

Reproduction Availability Warning: No confirmed reproduction manufacturer currently replicates Butler markings with certainty. Most "Series 1 early licence light repro" units are tooled from the later Lucas pattern, and sellers are not always transparent about which version is being sold.

For Concours or High-Value Restorations

For flat floor/welded bonnet cars (the earliest and most valuable variants), NOS (new old stock) or professionally reconditioned original units are strongly preferred over reproduction because:

  • Casting marks and lens stamping are inspection points for judges and serious buyers
  • Butler units are genuinely rare due to the short production window before Lucas absorption
  • Reproduction quality and authenticity cannot be guaranteed

For Driver-Quality Rebuilds

If the original light is damaged beyond use, reconditioning the original (if available) remains preferable to reproduction for authenticity purposes.

Next Steps

Clarify whether your car requires a replacement due to damage or if you're starting without a light. This determines whether original reconditioning is viable or whether sourcing becomes necessary.
