FAQs
Q1. Which positions can this red 7443 fill?
A1. Stop, tail and rear turn in a combined red lamp; a truck with a separate amber turn lamp needs an amber bulb in that holder.
Q2. Do both levels light in a 7440 holder?
A2. Only in a socket with two live contacts. A 7440 socket has one, so the bulb lights on one level and the brake or tail function is lost.
Q3. Will the turn signal flash fast?
A3. On some trucks, because 16W per pair sits below a 21W filament. If it runs fast or a message appears, support ships a free decoder for that circuit.
Q4. Is red behind a red lens the right match?
A4. Yes. The lens filters red light anyway, so a red source keeps its output, while a white bulb behind the same lens gives up most of it as heat.
Q5. Is 8W enough for a brake lamp in daylight?
A5. It is the dimmer of the red pairs at 1,800LM, so it suits tail and turn duty better than a brake that has to read in direct sun.
