Question in regards to how the front clearance bulbs next to the H-light operates...On the 95-96 max's with headlights on, it runs at a lower wattage until you put your signal on. In that case it lights up brighter. Duh, right? So are both filaments in the bulb lighting up? I'm trying to understand how cutting the nub off of the bulb would allow for all bright all the time. Thanks

Same question for our rear red tails. They are duel filament. So in theory, one could clip the nub on 2 of the 4 duel filament bulbs to keep them dim while the remaining two light up as usual. Is this correct? Thanks.

 

When you hit the turn signal, both filaments come on. When you cut one nub off and turn the bulb around, you are lighting up the brighter of the two all the time.

The rear brake lights are 1157 dual filament bulbs and the rear tail lights are 1156 single filament bulbs. When you hit your brakes, the second filament in the 1157 brake light comes on. You would not want this to be on all the time.

 

Well, what I was inquiring about on the rear is the brake lights on the rear. We have 4 separate bulbs for our red tails. When the parking or H-lights are on, they constantly run at a lower wattage. When the brake is applied, all four light up brigher. When this happens are both filaments energized? If so, I was thinking of cutting the bright nub off and running two of the four lights dim all of the time. I've seen some of the euro cars are like that. They have 4 red tails and only 2 are brighter when the brake is applied.

 

Not exactly sure, what you’re going for, but I wouldn’t want to “lower” the brightness of my brake lights. In good weather it may not be a problem, but during inclimate weather (rain, fog, snow….) it would make you hard to see, shorten the distance for someone behind you to react.
Also note, in a lot of Euro countries they require an “extra” rear light (usually on the drivers side rear) for just this reason!

 

That is a good point about the inclement weather comment.

What I was wanting to experiment is having our red tailights do the exact same thing as before but only the inner two red tailights get brighter when applying the brake and the outer two remain at the lower running light wattage. It was just an idea but you have a good point about the bad weather part. I use to have a Volvo which had those BRIGHT rear lights and they sure helped.
