plug light in without spark?
Anti-spark power supply connectors make the contact in 2 phases
Phase 1: A series resistor allows possible capacitors to get charged less violently. This reduces inrush current peak and the spark when the contact is not established.
Phase 2: The extra series resistor is bypassed to create the final low resistance contact
If your lights have electronic current regulator they quite surely have a capacitor, too. ==&gt; The anti-spark connector can be useful.
What is a good type cannot be solved here without knowing the specs of your lights and the used power source.
If it happens that you use old school halogens, they also take a hefty starting peak when they are cold. If you are unlucky you may burn the connector if you let the series resistor be active too long. Inrush limiter for a halogen must be designed with different specs. The linked ones were made for hobbyist drone batteries.
Every item which is plugged in separately to existing voltage needs its own ant-spark connector because the the resistor works when the connector has already made the 1st touch but is slliding towards the final &quot;connected&quot; -position.
