legal driving lights without the barndoors opening?
you mean you put HID's in the turn signal spots?
am i misunderstanding, or do you have some pics?
"Legal Driving Lights" probably refers to Daytime Running Lights, which are output-restricted by law everywhere they are mandated or legal.
Low beams (barndoors up) are technically too bright for DRLs and are typically illegal to use as DRLs unless the car didn't come equipped with DRLs from the factory. Also Low Beams do not project straight ahead, which is a DRL requirement.
If a car does use the main headlamps as DRLs they are wired so the hi-beam is used and it's wired in series (1/2 light output, beam projecting straight ahead; series wiring creates a 24V load on 12V supply) or a dedicated DRL lamp is in the housing.
Allowable lamp colour varies by jurisdiction; in some places you need white lamps for DRLs in others you can use the ambers. If you are using the smaller lamps as DRLs it's mandatory to use the outermost lamps found on the front of the vehicle.
Everyone has slightly different rules (UK, EU, non-EU Europe, Japan, etc) but the above is pretty consistent.
With Canada-market Miata DRLs (mandatory when the 90 was introduced) the DRLs are the ambers in the turn signal housing, which come on as soon as you release the parking brake with the engine running, regardless of where the main lighting switch is set.
If you wanted to mimic the operation of the JDM DRLs having them wired to come on with parking brake release is an easy way to do it. Don't use the existing brake warning lamp circuit, install a switch, relay. Otherwise your DRLs would go out with any brake malfunction (when the brake lamp goes on).
