FAQs
Q1. Where does this red pair belong on the truck?
A1. Stop, tail and rear turn in a combined red lamp; where the turn lamp is separate and amber, this pair covers the stop and tail only.
Q2. Does it need a specific holder?
A2. Yes, a 7443 holder with two live contacts, since the pair uses both levels; in a 7440 holder with one, one function stays dark and the pair reads as single-level.
Q3. Will it cause hyper flash?
A3. Usually not: 30W per pair is close to a 21W filament pair and the resistor steadies it. If the rate runs fast, support ships a free decoder.
Q4. Is 3,000LM too bright for a brake lamp?
A4. No. The bright level is the brake, so 1,500LM per bulb sits above the tail level by design, and the driver keeps the two states apart.
Q5. Does it run cooler than the halogen?
A5. Yes, at the lens: 30W per pair against 54W for two filaments, and the fan moves the heat away from the lens instead of soaking into it.
