This Lamp Bar is a RevingtonTR development, which unlike the 'rally' lamp bar does not require the removal of the front bumper. The lamp bar is supplied in a natural dull finish (not polished) which customers can polish, especially the visible parts, if they so choose. This lamp bar can be fitted straight to the car with the bumper in situ and also allows the bonnet to open normally (assuming 5" lamps are fitted). The lamp bar bolts to the inboard pair of bumper iron bolts, which fall in the same place on all bumpers fitted to TR4, 4A, 250, 5.
Once in place the bar can then be fitted with 5" or 7" fog or auxiliary driving lights. The lamps are positioned 420mm apart and extend forward from the centre line of the lamp bar 82mm. It is worth noting that if very large lamps are to be used that would foul the bonnet when it is opened, the lamps can be hung down off the lamp bar too.

Please note that the overriders fitted to TR4 front bumpers are much closer together than those fitted to the TR4A, TR250 and TR5. With the spacing between the lamps at 420mm as mentioned above, the inboard edge of a TR4 overrider is 65mm from the centre line of the lamp, where the lamp is at its widest. This dimension being 250mm on a TR4A, 250, 5 as the overriders are much further apart.
If 65mm (TR4 only) will not accommodate your chosen lamps, then we suggest purchasing an extender bar RTR8428-1. This stainless steel strip is 4mm thick, 30mm wide, and is intended to be bolted between the two lamp mounts. The strip has nine 5/8" (16mm) diameter holes along its length and can accommodate your lamps at a spacing to suit you including one central lamp if this is legal in the territory where the car will be used.

 

Before attempting to fit the lamp bar, please ensure all the right fittings are employed between the bumper bar and the bumper irons (cupped washers of the correct thickness). the lamp bar will not fit well if the bumper irons are too far inside the bumper bar.

The lamp bar is intended to fit with the lugs supporting the lamps very close to the top of the bumper bar. As our cars are 60 years old, bumper fitments will vary from car to car. If when trial fitting the bar, tighten the bumper bolts slowly and ensure there is clearance to the top of the bumper bar. If there is, great, continue to tighten. If not,  try moving the lamp bar up as it is probably tight against the top of the bumper. This might entail filing the mounting holes out where the bar mounts to the bumbler irons, or a small amount  of material can be removed from under the lamp mounting lug, just where it touches the top of the bumper bar.

If the lamp bar needs to move further towards the body for it to sit nicely with respect to the top of the bumper bar, washers can be introduced between the lamp bar and the bumper irons.
