You don't need to convert the standard bowl, as your motor factor should be able to supply a 60/55 watt halogen bulb with a standard 55/50 watt bulb fitting. These bulbs are numbered P43 (I think) and put a marginal extra loading on your wiring, but not enough to cause any problems.
Any further help-just PM me!
I think I am going to examine the headlights once I collect the car tomorrow and decide how to proceed.
As a matter of principle I always use a separate fuse and relay for main and dipped headlights. Bit belt and braces it may seem, but have done it for all my previous / present classics.
No problems at all for switches then.
As I said above belt and braces maybe but.
Work in progress on my Husky wiring
Dynamo to alternator; +ve to -ve earth; feed through Lucas 4FJ fusebox with 35amp glass fuses provides 10 outlets which can be separately fused to suit application. Usually a relay used for each application too. Vehicle Wiring Products always know when I am doing a project!!
Measured against ease of finding 472 bulbs 3 prong type at higher wattage seems fair price to me
The 410 single notch bulbs are not stock items in most normal parts suppliers
Am I correct in thinking that 410 bulbs are only available in 45W / 40w configuration?
To me the 60W / 55W must be a better light.........
Ah ha... (puts M.O.T. tester's hat ON) strictly speaking the headlight units should have the "E" symbol on them, but ensuring the headlights meet "E.U." standards is normally a requirement dealt with by the manufacturer of the vehicle. Most M.O.T. testers will check the lights for brightness and beam angle & pattern. If they're satisfied on these they'll pass them. They'll only start looking for "E" letters on the glass if there's problem with the beam pattern or something is obviously amiss. (takes M.O.T. tester's hat OFF)
By the way, yellow headlights (for that quintessential "French" look) ARE legal, honestly! I've loads, if you want some!
If I am going to go the route I want then getting better is best options. Thanks for the information.There are some new Cibies in the Netherlands with the LHD to RHD switch and holes for the sidelights. http://www.renault4.co.uk/forum/threads/headlights-for-renault-4-import.7068/#post-43153
I'm running the cheaper Franzose lights in mine and the beam pattern is rubbish. I might one day change them for Cibie lights.
