What nation state or regulatory market did the 940 originate?

As BB says.

Yet is your 940 with glass bulbs or plastic bulbs. As the factory grey adhesive secure the lans and reflector body together embrittle and can fail, as on all US DOT crappy plati lenses.

You can restore these if they leaks.

Else, e-code that use H11 bulbs, two in each headlight. These can be halogen or LED.

BB has a lot of experience with these LEDS in Volvo.

Chart is not current. Many no longer make the 9004 bulbs for reflector style headlamps.

For Volvo 1991 Volvo 240, with crappy USDOT 9004 reflector style assemblies, I have the crappy and not so bright 9004s in the orange pack from Sylvannia.


Osram operates in markets than the crappy US DOT crappy lighting.


Philips NightGuide platinum no longer makes 9004.

Flosser and Hella make good halogens.

Eiko makes these for NAPA, not themselves. Not on that bulb liat:

two bulb pack.

There are wire harnesses to bring B+ to the haalogen bulb offloading current from the factory headlight that makes it a control voltage of something like this:

Ask Mr. Wagonmeister if this can fit in 940.

Also, the reflector style crappy USDOT 940 headlamps are made for use with halogen bulbs. If you want H11 high / low dual bulb, get ecodes and some makes of LED bulbs may work better.

May want to ask Turbobricks. Requires an account.

LEDs of the model for your headlamps may make a white-blue fl;are l.ike output to blind on coming motorists.

If you do not want a ticket, unless you are in Wyoming, ensure the LED bulbs you want are crappy US DOT legal. 15-30K lumens per LED bulb pair will blind on coming drivers. Though most roadway code enforcement does not bother with using photometrics / luminosity (lumen) scanners to check how bright your bulbs are. US DOT (crappy) and states have controls on how bright your headlamps can be. Not sure what the statutes indicate, whether enforced at all.

9004 halogens of performance may be up to 6-8k and not much more.

Also, halogens in the yellow to yellow white can pick on snow and rain drops and more yellow cast beam farther as longer yellow-white wavelength cast further for distance. Some LED do this of use a PLC or modbus/canbus to change color yet some do it at extreme and goofily and maybe illegal to US DOT.

What nation state or regulatory market do you 940 come from or where are you now? What bulbs do you use by model? I'll guess 9004 as BB surmises.

Hope that helps.
