Much depends on the age of your Morgan and the regulations at the time of 
manufacture. There was a point in time where position lights on the wing did 
not meet the current regulations and a light in the headlamp became necessary. 
At one point this became a dim/dip arrangement and then later on a pilot light 
in the headlamp. When the Morgan left the factory the wing top position lamps 
where often left unconnected. In some cases the owner or the dealer made the 
connection between the feed to the pilot lamp, and the position light.

The position lights will be fed from the same feed as the pilot bulb in the 
headlamp, they are in parallel, so if one bulb fails it will not affect the 
other.

As both lamps are out, and the headlamps work,  it is unlikely to be an earth 
fault. The power feed to the sidelights  is normally made via bullet connectors 
which are usually open to the elements under the front wings. Worth having a 
look and tugging at the wires to see if any are loose. Look on both sides in 
case the offside feed comes from a junction on the nearside.

Good luck

Choice of title deliberate - anybody who drives around on “sidelights” should 
be nicked: by switching any lights on at all the driver’s acknowledged that 
visibility is bad, so dipped headlights has to be the minimum illumination… 
rant over!

My car has the wing-top lamps, the off-side one of which has ceased to 
function. NOT a blown bulb, replacement makes no difference. Both headlamps 
(dipped and main beam) work perfectly.

BUT, at the first position of the light control stalk, only the near-side 
wing-top lamp illuminates together with a small bulb inside the near-side 7” 
headlamp. Nothing at all on the off-side but, as I said above, on the second 
position of the stalk both headlamps come on and function correctly…

I’ve never before noticed these small bulbs inside the headlamps, why are they 
there and do they normally come on with the wing-top lamps?

Are they wired in series with the wing-top lamps so that, in my case, a circuit 
failure has caused both off-side bulbs, i.e. the wing-top one and the small one 
within the headlamp, to fail?

Where should I look (other than in the ’phone book for Stratton’s service 
department, of course)?
