Dipsik  +  580019 Sat, 25 Oct 08 09:18 AM Hello, would you please check the sentences below and tell me whether there are any mistakes there? red - main clause green - noun clause orange - relative clause blue - adverbial clause (of any kind) New traffic lights have been developed because the existing ones are difficult to see in strong sunlight and sometimes appear to be ´on´ when actually they are in the ´off´ position. It is claimed that the new signals overcome these problems and that they can contribute to road safety. The new signals will look similar at a distance, but close up the driver will notice a pattern of holes. (compound sentence) When the new light is off, it will look a lot blacker. The main change is in the lens, which in the new lights consists of small ´lenslets´ that channel the reflector´s light through 2000 holes in the mask. Thanks a lot in advance L.

Everything is right except your last sentence.  It consists of a main clause followed by a relative clause (which...mask modifying lens) with an embedded relative clause (that...mask modifying lenslets). The main change is in the lens, which in the new lights consists of small ´lenslets´ that channel the reflector´s light through 2000 holes in the mask. .
