Title: CB 400/4 Headlamp
Post by: Nurse Julie on November 14, 2016, 05:23:33 PM
I'm sure this topic has been covered before but, I can't find I anywhere.
The inside reflector on my headlamp has got quite a bit of rust at the bottom so I'm going to get a new headlamp. At present, the original Stanley Honda one is fitted but I would like more powerful bulbs in the new one, halogen maybe. Has anyone purchased one recently and where from? I have a new Lucas 7" one here but it's too big for the rim, therefore won't fit  :'( :'(
Ta in advance
Julie xx

I'll open the jiffy bag that I never got round to sending today and I'll put a bulb in with it.  It's brighter than the OEM ones. Actually, let me know what your plans are before I send it but I used a superdream headlamp from MandP.  It cost about 31quid and worth every penny.

D.S.S. has pattern ones, £29 +V.A.T. and post, just don't tell Trig where you bought it!

Yes, I saw that Hairy and was tempted but, I don't like the flat front on the glass, I like the original which is more convex. I can't talk to Trig about this, the headlamp is attached to wires and he just ignores me when I talk about electrics and wiring, as you know it's his least favourite subject, so on my own with this one  ::) ::) ::)

M&P is cheaper.  It isnt flat like the superdream ones.

The wires lead to a plug on the back of the main bulb, so you can't go wrong there, and the 2 wires to the sidelight bulb, even a girly SHOULD :o :o be okay pulling one at a time and putting the new bit in it's place. The flat lens on the light unit is very retro aftermarket 70's style, so wouldn't look out of place as a period modification.

The marking on the front of both units reads 'XANADU' - same unit in both cases?
The DS one looks convex to me, looking at the picture of the light unit sitting on the glass.
Only thing I'm not sure about is the lamp connector - I thought the H4 bulb used a different connector to the original. I had to change mine when I fitted the Cibie unit.

The DSS one is definitely flat compared to the Original.

The one on the left is my Stanley original Honda, the right is a DSS replacement.

I've just compared original with the M & P one; they both have a 20mm (ish) convex.  I'll still post the holder, it's been in my van all day but I haven't been past a Post Orifice.  Do you want the blub as well?

I bought a H4 53/4 inch light unit,

 depending on your generator power you can fit a 35w/35w  or 55w/60w  or I think a 100w H4 bulb,

 my light has a pilot bulb as well,

 I think about £15 from a local motor factors,bulb about £4

That's a good price John. I'm assuming it wasn't for your 500/4 as 5 3/4 would be a bit small  :o :o, (I only know this as I have just measured a 500/4 we have here and it's 7"). My headlamp also has the pilot light and I have 35w/35w fitted, which gives less than 1 candle power I reckon, on main beam !!!

  it is for my RD125 ,always try to buy from a motor factors,should get close to trade price,

  this is it with the H4 bulb   35w/35w

If you're using an H4 bulb. You don't need to go 100watt to get a brighter beam. Both Ring, Lucas, Osram & a few others do 55/60watt H4 that give a much brighter light. from 50% up to 120%. Don't go to Halfords as they are too bloody dear. A local Motor Factor should be able to help.

I've increased mine to 55/60W.  The only downside is, with the headlamp on, braking to turn a corner, indicating for the corner as well, blows the 15A main fuse causing the engine to die.  It happened twice.  Increased fuse to 20A, now OK.

I reckon a 5 3/4" light unit would fall through the Honda rim.
The aftermarket Cibie units measure 5 3/4" across the lens and have an adaptor ring that fits inside the standard rim to reduce the hole diameter.

For H4 bulbs you could try these: http://www.ebay.co.uk/itm/351595613785?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
They are supposed to consume 20% less power, which to my mind defies the laws of physics, but seem to be well reviewed.
This link originally came from an earlier thread on here, their price is very good.

Going back to  the original subject - re rusting reflector - what about re-silvering, my chromer gave me a contact to get it done, I got it parted from the glass ok but haven't had it done yet.
Anyone tried it ?
Title: Re: CB 400/4 Headlamp

That's another idea I hadn't thought of.

Have you got, or could you get, an idea of cost from your contact?
It's a process that inherently doesn't feel as if it would be cheap, but I have no idea how many pennies you would be looking at.

I had a 1970s Ducati headlamp bowl re silvered recently....it was an unobtainable item and I had no real choice; it came it at about £120 by the time it was back on the bike...far from cheap but it did the job.

Excuse my language but f**k, that's expensive. Ok if no other options but luckily there is with a CB400/4

That is a lot of pennies but I guess it depends on the condition, if it's a rust bucket then the prep' could take a long time. Mine only has a bit of rust around the pilot light and I'd like to keep it original. I'll send some pics off to the plater ASAP and try to get a ball park price from him.
