incandescent lamps to get the best of both worlds: LED luminosity and incandescent snow-melting ability.
Resistance is futile
Mixing LEDs and incandescent might seem a great solution from a safety perspective, but it can also lead to maintenance challenges as the two kinds of lamps draw differ- ent amounts of current and offer dif- ferent resistance levels – both being higher with the incandescent – on a single circuit, which can require the addition of a resistance on the LED side to balance the circuit.
The LED’s lower current draw and resistance is the reason why some tech- nicians will often install them on other- wise all-incandescent lighted vehicles. Even if the electrical system is in bad shape, the LED offers so little resistance that it will still light, whereas an incan- descent bulb wouldn’t and the problem seems to be fixed.
“Shops are doing that now, because if they can’t find the high resistance connection to stop those lights from blinking or pulsing, then they put an LED lamp. It allows the lights to function again but the problem with that is when the issue shows back up again, you can’t mask it again for the second time; otherwise you’re just

creating more problems in the elec- trical system,” Russell says.
Besides, a quick LED installation will not always be a solution. If resis- tance is too high in a circuit, an LED might simply not light at all, con- trary to an incandescent. “They’ll dim, you can barely see them but they still flash. They might flash erratic, but you’re still gonna have illumination,” the Fanshawe profes- sor says of incandescent lamps.
Rust never sleeps
One way to eliminate unwanted resistance in a circuit is to keep the connectors clean and free of corro- sion. “A regular inspection and lubri- cation of the connectors with sprays such as dielectric grease is the key,” says Ferland, adding that such lubri- cants should never be used on elec- tronic module connectors, which are more sensitive to chemicals. Russell suggests using only electrical clean-
