this is quite a thread resurrection! But I will just say that, even though I'm on the wrong side of the pond, Daniel Stern has ben my go to person for lighting advice for 15 years now. He advised me to upgrade the factory euro (RHD) lights on my E24 to Cibie CSR units. These same lights are now fitted to my E9 (with relays and chunky wires on the low beams). Cibie no longer makes the CSR but if you find a set used, just buy them! Awesome lighting.
Daniel (Consult Daniel Stern Lighting <
[email protected]>) had the following to say:
Flat-face Cibies have been unavailable for quite a few years now, and the convex-face Cibies just recently were discontinued after deteriorating in build quality and performance for some time.
Daniel is now big on:
1. Kioto Headlamps, to him these are the most efficient (greatest amount of light on the road), best focused (most useful distribution of light), best-built (sturdiest glass and metal materials, most careful build quality) lamps of their type in this size -- he said they're significantly better in all three respects than the (discontinued) Cibie and (available but not worth buying) Hella lamps in this size, not to mention blowing away the off-brand junk.
2. His current best-pick bulbs are made by Tungsram (GE of Europe) and cost $78.36/set of four, that is two of the H4 high/low beam bulbs for the outboard lamps and two of the H1 high-beam bulbs for the inboard lamps. For data, please see bulb test results posted by his colleague Virgil at

3. He recommended adding a relay install kit RIK-4. The RIK includes all the needed relays, brackets, terminal blocks, terminals, plugs, sockets, fuses and fuseholders, all in very fine quality. You can DIY or have them build the kit.
4. For those of us with Euro's, or those of you opt for parking lights, you can either:
a) Swap on a set of the US/Canada front turn signal socket-housing assemblies (they take a 2-filament bulb with the bright filament for the turn signal and the dim filament for the position light), or if you want to keep your existing front turn signal housing -
b) buy a cheater dingus on ebay a set of these:

5. Daniel says the exterior signal lamps can safely be made 45% brighter with special high-efficiency bulbs available (only) through the Honda parts system.
The single-filament variety (replacing 7506, 1156, 1141, 1076, P21W, or P25-1) is

6. When it comes to connectors, he writes: It's best not to use the fold-over-and-crunch "Scotchlok" type taps. Much better, more durably trouble-free result if you use Posi-Taps,

Daniel typically responds late at night Pacific time, but the responses are very detailed. Again, great service and information. He knew all the variations of e9s.
