I will need to carefully drill a hole in the reflector to poke a bulb holder through
I may need to install sidelights into my non-sidelight headlamps. It suddenly occurred to me that my old Nissan had dim-dipped headlights, presumeably
using some kind of a voltage dropping circuit to achieve the lower light level.
Does anyone know if this is easily done with some simple circuitry and if Mr SVA would have any problems with this setup?
The problem with dim-dip headlights and why they stopped doing them is very simple. They damage the bulb so should need replacing more frequently. The upside is that due to lower surge they actually never needed replacing as much... it's a simple resistor I believe. The circuitry of our donor Sierra had them... looks quite simple to do, but whether it is or not is another matter.
Its actualy quite complex in the sierra using two relays and connecting the dip bulbs in series to give the dimming. Mr SVA wants to see side lights
which can be a separate bulb inside the headlamp housing.

Looks like Plan B will have to come into play then

The reason why dim-dip when out of fashion is it never gained the popularity in th rest of europe it had in the UK. However it is not acceptable
without sidelamps also being fitted.
The easy way to get it working is to use the relay and resistor from a Volvo 340 -- easy to remove it is mounted under the bonnet high on the
bulkhead. A lot of other manufacturers such as Rover mounted the dim dip relay and ressistor behind the front bumper below the the lh head light unit
-- this causes a lot of problems with corrosion of the termminals.
Having taken a closer look at my headlights, it is going to be very difficult to add a sidelight to them. I was planning to glue an LED into the
reflector, but as it is a delicate glass/ceramic composite I risk writing off the whole headlight.
It looks like a dim dip setup might be my only solution.
Before I start to go down this route, does anyone know if a dim dip light is ok for Mr SVA. I do not intend to use the dim dip feature - I just want
it to pass SVA.
Dim Dip is what it say's it puts the dip beam on dimly. You need separate sidelight bulbs for SVA. Can you use a front sidelight/indicator lamp ?
I didn't want to have to use an extra lamp to do the job. As it stands I have the main headlight (dip & main in one unit) and indicator units
(clear lense with amber bulb)
With a little bit of ingenuity I could put two bulbs (amber & clear) into the indicator housing but I am not sure if 'sharing' a light
will be ok for SVA either.
The sidelight shares with the headlight, what's the difference? It's worth a try, you can always ring an sva station and ask them they are very helpful.
