Overview

Datsun 1200 uses the standard 7-inch round sealed beam headlamp. 12V large round headlights from *any* car will fit circa 1956-1986. Original equipment was Koito, Ichiko (IKI), Toshiba or GE.

NOTE: Large round (7") headlights from *any* car will fit the Datsun 1200.

Europe

H4 is high-intensity lamp, not a regular headlamp. Not legal in many countries for highway use.

The headlight type matter for the country driving type. Whether you have an LHD or RHD car, you mut use the same headlight to match the road. For example, in France they drive on the right -- typically (but not always) using LHD cars.

RHD vs LHD

The left side and right side headlamps are the same - each car uses two of the same headlights. However, RHD (right hand drive) pattern is reversed from LHD - the lens pattern and high cutout is on opposite sides. If you fit RHD headlights in a LHD country or vice versa, it will blind oncoming traffic. So when importing cars, change the headlights to the locally approved type. Or you could fit tape to the lights as is done for visiting cars in Europe.

Rectangular Head Lamp

Square Headlights were IKI supplied. B122 starting in October 1989 uses square headlights as did B140 in 1990.

NOTE: These appear to be same as B310 square headlights with buckets swapped left/right. But the adjuster screws and grommets are different.

VENDOR: RockAuto.com Product: headlight bulbs for Datsun 1200

CAUTION: Any headlight marked "DOT Approved" is bogus.

7" round sealed beams are type 6012/6014 for a two-headlight system (a single large round lamp on each side of the car). These are "dual beam" lights (two-filament), encompassing both regular and high-beam in the same sealed beam unit (sealed so the reflector will not tarnish). Recommended is type H6024, which is a direct-replacement but higher power (65W/35W) bulb. About $13 on Amazon.com

These are type 6012/6014 for a two-headlight system (a single large round headlight on each side of the car). These are "dual beam" lights (two-filament), encompassing both regular and high-beam in the same light.

Note that the original specification 6012 headlamp is only 50W/40W. You can substitute the brighter 6014 which is 60W/50W. Type 6015 is a longer-life bulb, but more expensive.

Specification

Alternatively, and recommended, H6024 (65W/35W) is a halogen replacement. Halogen is a brighter light, and now available in shades of blue, gold, white. Street-legal in USA.

The brighter 6014 is as inexpensive as $3. See RockAuto headlights for Datsun 1200

Brightness

Instead of limiting the brightness (candlepower) or flux (lumens), FMVSS limits the power.
FMVSS 108

S7.3.5 Type D headlighting system. (a) A Type D headlighting system consists of two Type 2D1 headlamps ...

(b) The maximum wattage at 12.8 volts (design voltage): 65 watts on upper beam, and 55 watts on lower beam.
LUMENS per SAE-J1383
2D1 lower: 1320 maximum
2D1 upper:  800 minimum

H1   55W     1550
H2   55W     1450
H4   60/55W  1650/1000

As can be seen, H4 type 60/55W bulb meet the spec: more than 800 upper beam, less than 1320 lower beam. Sealed beams are also commonly available; 65/55 (H6024 Xenon) and 60/50 (H6014). Although it seems Sylvania has down-graded the H6024XV to 60/40 (maybe due to overheated wiring)?

High-power Headlamps

H4 euro-type, Halogen, etc that require upgraded wiring.

NOTE: LED headlights can be brighter without using higher power and so work with the stock wiring.

H4 headlamps are apparently legal for use on USA roads -- if the bulbs are 60/55W (this is to prevent blinding oncoming drivers). In other words, about the same brightness as H6014/H6024 Halogen sealed beams. Higher watt H4 bulbs are for off-road use only. Higher watt bulbs require higher-wattage capable wiring (factory wiring was designed for 50/40W headlamps).

HID lamps put out up to 1600 lumens -- far more than round sealed beams -- but with a wide dispersal pattern and a sharp vertical cut-off. So they light up the road surface more, but don't light UP the horizon.

For H4 lights, the stock Datsun 1200 headlight connectors are large enough gauge. Only replace if corroded.

For most H4 lights, the stock Datsun 1200 wiring is large enough (12 gauge for high beams). However to prevent fuse problems, use a wiring relay.
