Quad Beam TDI --- Low Beam & High Beam Together

I've owned pickups in the past and bought "quad beam" kits to enable the low beams to kick on at the same time as the high beams, but when I look at my 2003 Jetta TDI, it seems like they both stay on without a modification, or the high beams are just really bright or something. Could someone clarify for me, does a kit exist to turn the high and low beams on for my model car, or does this already happen as a factory default, or are they the same bulb but different power allotments or something? Need help here please, searching the forums has proved nothing. Thanks all.

hmm

I have a 03 aswell, I notice that if I flip my high beam switch forward, just high beams are on, if I hold it back (towards me) they are both on..huge differense in brightness

I imagine that over extended periods of time you're liable to melt the housing if you keep them both on.

my old 88 Camry had this function with the 9004 bulbs.

This is not a good idea. With the high and low beams on at the same time, too much light is put right in front of the car. That makes it harder to see far away. Also, this will make the bulbs run a lot hotter then they're designed to/

In the golf the high and low beams are in "seperate" lamps, I do not think that this will be an issue.

+ VW do it to "flick" the lights

As long as you have separate bulbs it should be ok I think but if you have single bulbs with a dual low/high filament then you shouldn't enable both.

So it could be a good idea if you have a Golf or have swapped the headlights with dual lens ones.

I read that my headlights (they've been swapped) were meant to have both on but I haven't done the mod yet.

The golf and passat, which have separate lamps for high and low beams, already have this. The jetta, which has a dual filament lamp, does not.
