Thinking of buying digital headlights

(They do come with fingerprints? )

LED or even HID headlights may look too "modern" depending on the general appearance of your classic. If you have a light issue, try to find a couple of European specs. H4 headlamps, make sure your electrical circuit is in good shape, I would go with relays to ensure a full current supply to the bulbs (and to save the light switch too against melting).
